For some reason I cant get the most basic operations to calculate in my program. Im sure its something painfully stupid but here it is.

Private Sub Form_Load()
Dim iLogFail As Integer
iLogFail = 0
End Sub
 

Private Sub Command8_Click()
If iLogFail = 3 Then
    MsgBox "works"
End If
 
iLogFail = iLogFail + 1
End Sub
 

it doesnt work. and my var isnt initializing. it should be 0 but its empty. im going crazy here what am i doing wrong?

Hi there,

in order to reuse the same variable again and again make sure u declare and the variable in the general declaration area or in a module file.. good luck my fren.. :)

Private Sub Command8_Click()
  If iLogFail = 3 Then
    iLogFail = iLogFail + 1
    MsgBox "works"
  EndIf
End Sub

sashi be right but, being me, i have to give some explanation. This is all about scope. where a variable can be use depends on where it is dimentioned. putting a variable in a subroutine (like your form_load) says "i want to use this varaible, but only in this subroutine". putting it in general declarations says "i want to use this varaible, but only on this form", putting a variable in a module says "i want to use this variable anywhere in my project no matter how many forms i have." trying to access a variable outside of its scope will create a new varaible. to avoid mistakes like this, type "option explicit" at the top of your general declarations and it will tell you when a variable is undefined. handy for finding simple mistakes like this.
