.net - Why Only Getting One Output Value (and No Debug Output) From This Code?
Jun 14, 2012I'm just going to throw all my code in here in case there's something wrong with a piece of the code not in the "SelectName()" sub.
Module Module1
Dim selectednames As String = ""
Dim index As Short = 0
Dim inarray As Boolean = False
[code]....
Here's an image of what it does (I suppose you can see what went wrong)13 inputs, 3 outputs expected, only 1 output given.As from what I've figured out so far, it's doing the correct amount of loops etc. It's just as soon as it starts generating the "winner" for the 2nd game key it doesn't get a string value from namesarray.Also, why is
For x = 0 To totalnames - 1
Debug.Print("namesarray(" & x & ") = " & namesarray(x))
Next
not giving me a debug output?
