Answer 1

When creating labels, insert one more line:
S1.Name = "MyLabel" & X & Y
When accessing the label:
Dim MyCurrentLabel as Label
MyCurrentLabel = CType("MyLabel" & X & Y, Label)
Then you can do things with the current label:
MyCurrentLabel.Text = "Hello World"

Answer 2

Now it is something like this, so it want to change the colour to red if it is paid according to database.
Thanks
