pass user selected range into array then into userform text boxes - arrays

Question

I am trying to have my code prompt the user to select a range of data of 3 width and variable length. There will only be 30 values those with some rows being blank. I want to have these 30 values populate into 30 text boxes in a userform of mine (this is so values don't have to be manually entered). I looked around and figured my route should be Application.Inputbox and then pass it into an array were the blank rows can be weeded out with for loops. I don't know how to pass the user selected table into a 2D array though.
Sub selectRange()
Dim r(1 To 14, 1 To 3) As Variant, ran As Range, calB(1 To 30) As Long, i As Integer, j As Integer, k As Integer, l As Integer
dozerCal.Hide
Set r = Application.InputBox("Select the Cal B table.", Type:=8)
For j = 1 To 14
For i = 1 To 3
If Abs(r(j, i)) > 0 Then
calB(l) = r(j, i)
l = l + 1
End If
Next
Next
lx = calB(1)
ly = calB(2)
lz = calB(3)
rx = calB(4)
ry = calB(5)
rz = calB(6)
ix = calB(7)
iy = calB(8)
iz = calB(9)
sx = calB(10)
sy = calB(11)
sz = calB(12)
p1x = calB(13)
p1y = calB(14)
p1z = calB(15)
p2x = calB(16)
p2y = calB(17)
p2z = calB(18)
lfx = calB(19)
lfy = calB(20)
lfz = calB(21)
lrx = calB(22)
lry = calB(23)
lrz = calB(24)
rfx = calB(25)
rfy = calB(26)
rfz = calB(27)
rrx = calB(28)
rry = calB(29)
rrz = calB(30)
ActiveWorkbook.Close
dozercall.Show
End Sub
Thanks in advance for everyone's help.

Edit: I missed that you were using the input box wrong, however I will leave this answer as it presents a way to collapse a variable range of user input from a multidimensional array into a single dimension array.
This should get you started. Basically it will read the user's input, dynamically create a one-dimensional array of the correct size (rows * columns), and read all the values in the range the user selects to this one dimensional array. It will then loop through the one dimensional array and print the values back out to the window.
I think this is what you're looking for, but if you need further clarification I can add some. I added comments so you can see what each section is doing.
Option Explicit
Private Sub TestArrays()
Dim calBTemp() As Variant, calB() As Variant
Dim i As Long, j As Long, x As Long
Dim rngInput As Range
Set rngInput = Application.InputBox("Select the Cal B table.", "Select Range", Type:=8)
'Read the user input, check for empty input
'If empty input, exit the subroutine
If Not rngInput Is Nothing Then
calBTemp = rngInput
Else
Exit Sub
End If
'Create the one-dimensional array dynamically based on user selection
ReDim calB((UBound(calBTemp, 1) - LBound(calBTemp, 1) + 1) * (UBound(calBTemp, 2) - LBound(calBTemp, 2) + 1))
'Loop through our multidimensional array
For i = LBound(calBTemp, 1) To UBound(calBTemp, 1)
For j = LBound(calBTemp, 2) To UBound(calBTemp, 2)
'Assign the value to our one dimensional array
calB(x) = calBTemp(i, j)
x = x + 1
Next j
Next i
'Loop through our one dimensional array
For i = LBound(calB) To UBound(calB)
Debug.Print calB(i)
Next i
End Sub

So I just wasn't using the Application.Inputbox right. If you return it as a range it will configure to the proper sized 2D array it seams and you can call/manipulate data from there. Here is a working sub.
Sub selectRange()
Dim ran As Range, calB(1 To 30) As Double, i As Integer, j As Integer, k As Integer, l As Integer
dozerCal.Hide
Set ran = Application.InputBox("Select the Cal B table.", Type:=8)
l = 1
For j = 1 To 14
For i = 1 To 3
If Abs(ran(j, i)) > 0 Then
calB(l) = ran(j, i)
l = l + 1
End If
Next
Next
lx = calB(1)
ly = calB(2)
lz = calB(3)
rx = calB(4)
ry = calB(5)
rz = calB(6)
ix = calB(7)
iy = calB(8)
iz = calB(9)
sx = calB(10)
sy = calB(11)
sz = calB(12)
p1x = calB(13)
p1y = calB(14)
p1z = calB(15)
p2x = calB(16)
p2y = calB(17)
p2z = calB(18)
lfx = calB(19)
lfy = calB(20)
lfz = calB(21)
lrx = calB(22)
lry = calB(23)
lrz = calB(24)
rfx = calB(25)
rfy = calB(26)
rfz = calB(27)
rrx = calB(28)
rry = calB(29)
rrz = calB(30)
ActiveWorkbook.Close
dozerCal.Show
End Sub

Answer 3

This code will do the trick (and forces the user to select 3 columns and 14 rows):
Sub selectRange()
Dim selectedRange As Range
Dim errorMessage As String
errorMessage = vbNullString
Dim ran As Range, calB(1 To 30) As Long, i As Integer, j As Integer, k As Integer, l As Integer
Do
'doesn't handle cancel event
Set selectedRange = Application.InputBox("Select the Cal B table.", _
Type:=8, Title:="Please select 14 rows and 3 columns" & errorMessage)
errorMessage = "; previous selection was invalid"
Loop While selectedRange.Columns.Count <> 3 Or selectedRange.Rows.Count <> 14
For j = 1 To 14
For i = 1 To 3
If Abs(selectedRange.Cells(j, i)) > 0 Then
calB(l) = selectedRange.Cells(j, i)
l = l + 1
End If
Next
Next
