[RESOLVED] Variable not retaining value when exiting sub.

Hi,
Can someone explain why a public variable is not retaining it's value when exiting a subroutine.

I want to search through an array and if a condition is hit then the subroutine exited (thereby holding the index value of a variable named MarkerNo)

The variable is dimmed in a separate module as public.

Code:

---

    Public Sub FindMarker()
        For MarkerNo As Integer = 0 To UBound(Markers)
            If A(MarkerNo) = B Then Exit Sub
        Next
        MarkerNo = -1 'Return -1 if not found
    End Sub

---

if you have it declared public in a module:

vb Code:

Public Sub FindMarker()
    For MarkerNo = 0 To UBound(Markers)
        If A(MarkerNo) = B Then Exit Sub
    Next
    MarkerNo = -1 'Return -1 if not found
End Sub

Putting "As Integer" in your for loop declares it again for use within the loop ONLY

ohh of course..
Thankyou.
