Variables

[Cndn]

For some reason, the following code doesn't work, how come?

Form_load()
Dim Number as integer
Number = 2
End Sub

Command1_click
Number = Number + 2
msgbox Number
End Sub

This code also will not work

Form_load()
Dim Number as integer

Dim Number2 as integer
Number2 = 2

Dim Number3 as integer
Number3 = 3

End Sub

Command1_click
Number = Number2 + Number3
msgbox Number
End Sub


How come???

It's all to do with the scope of the variables. If you declare a variable in a procedure you can only use it within that procedure.

Put
Option Explicit
at the top of every Form, Module or Class and the Compiler will tell when a variable is out of scope..."Variable Undefined". Go to Tools / Options / Editor and check "Require Variable Declaration". That will put the Option Explicit at the top ov every new module,
