TheDcoder,

Can you give an example script where this happens? Although there should be no problem in most cases, I can imagine circumstances where it might cause difficulties.

Can you please describe the scope where you want to use the variable (in the whole script, only a function)?

It is a little difficult to answer your question when you cannot explain what you're after. As water alluded to, declaring a variable more than once depends on the scope of that variable. We really need an example of how you are thinking of putting this to use - help us help you

; Testing variables with Global Scope

Global $var_global = InputBox("Testing Global Variables", "Please enter anything: ")
Global $var_global = InputBox("Testing Global Variables", "Please enter anything: ")

; Results:
;
; 1st declaration = The
; 2nd declaration = Dcoder
;
; Result = Dcoder

MsgBox(64, "Result", "Result: " & $var_global)

; Testing variables with Global Scope

Local $var_local = InputBox("Testing Local Variables", "Please enter anything: ")
Local $var_local = InputBox("Testing Local Variables", "Please enter anything: ")

MsgBox(64, "Result", "Result: " & $var_local)

; Results:
;
; 1st declaration = The
; 2st declaration = Dcoder
;
; Result = Dcoder

; Testing variables with Dim Scope

Dim $var_dim = InputBox("Testing Dim Variables", "Please enter anything: ")
Dim $var_dim = InputBox("Testing Dim Variables", "Please enter anything: ")

MsgBox(64, "Result", "Result: " & $var_local)

; Results:
;
; 1st declaration = The
; 2st declaration = Dcoder
;
; Result = Dcoder

; Conclusion: Declaring a variable with any scope a 2nd time will result in loss of data in the variable

Following the AutoIt naming conventions doesn't result in problems like this happening. Oh, and Dim is kind of frowned upon if not converting a non-Array variable to an array.
