Reference an array declared in a different userform - arrays

Question

I'm not an experienced VBA programmer but I've been trying to create an Excel Spreadsheet that is able to manage a basketball team.
In it I've got a primary userform where I have declared an array, 'selectedPlayers'.
This primary userform has a for loop that starts up the secondary userform 'i' times.
I have not been able to access the primary userform's 'i' and 'selectedPlayers' from the secondary one.
I've been able to find a workaround the 'i' by creating a non-visible textbox in the first userform, that I'm able to reference from the second one.
I've tried declaring both of them as public, but yet I'm not able to call upon it from the second userform.
part of the code for the first userform:
i = 0
Do While Not i = Int(txtNumberPlayers)
frmGameDataSecondary.Show
i = i + 1
Loop
second userform:
Private Sub cmdDone_Click()
frmGameData.selectedPlayers(frmGameData.i) = lbxPlayer.Value
Unload Me
End Sub
Private Sub UserForm_Initialize()
With Me.lbxPlayer
For Each LR In LO.ListRows
exitSequence = False
For k = 1 To Int(frmGameData.txtNumberPlayers)
If frmGameData.selectedPlayers(k) = blablabla.Value Then
exitSequence = True
End If
Next k
If !exitSequence Then
.AddItem blablabla.Value
End If
Next LR
End With
End Sub

Answer 1

The main problem is that array contents are cleared after the sub is finished.
I was also messing around with this idea and there is a really good thread I started with tons of great information from various awesome people

Forms in VBA are Objects, and can be treated like any other Class module. This means that you can add properties to them. If you need to pass information back from a form, all you need to do is grab a reference to it, then Hide it instead of Unload it. Treat it like a dialog and let the calling code handle it's create and destruction (I'm assuming from your code that it is modal).
Something like this:
In the first UserForm:
For i = 0 To 1
Dim second As frmGameDataSecondary
Set second = New frmGameDataSecondary
second.Show
'Execution suspends until the second form is dismissed.
selectedPlayers(i) = second.Player
Unload second
Next i
In the second UserForm:
Private mPlayer As String
'This is where your returned information goes.
Public Property Get Player() As String
Player = mPlayer
End Property
Private Sub cmdDone_Click()
mPlayer = lbxPlayer.Value
'Control passes back to the caller, but the object still exists.
Me.Hide
End Sub

You can declare properties inside of parent form which will manipulate the array from outside. The child form needs to have a reference to parent so it can call this properties. HTH
Parent form
Option Explicit
' I have not been able to access the primary userform's
' 'i' and 'selectedPlayers' from the secondary one
Private selectedPlayers As Variant
Public Function GetMyArrayValue(index) As Variant
GetMyArrayValue = selectedPlayers(index)
End Function
Public Sub SetMyArrayValue(index, newValue)
selectedPlayers(index) = newValue
End Sub
Private Sub UserForm_Click()
Dim i
i = 0
Do While Not i = Int(txtNumberPlayers)
With New secondaryUserForm
Set .ParentForm = Me
.SetIndex = i
.Show
End With
i = i + 1
Loop
End Sub
Private Sub UserForm_Initialize()
selectedPlayers = Array("A", "B", "C")
End Sub
Child form
Option Explicit
Private m_parent As primaryUserForm
Private m_index As Integer
Public Property Let SetIndex(ByVal vNewValue As Integer)
m_index = vNewValue
End Property
Public Property Set ParentForm(ByVal vNewValue As UserForm)
Set m_parent = vNewValue
End Property
Private Sub cmdDone_Click()
' frmGameData.selectedPlayers(frmGameData.i) = lbxPlayer.Value
m_parent.SetMyArrayValue m_index, "lbxPlayer.Value"
Unload Me
End Sub
