I tried a global variable with the following code.

global x
set x to 2
set x to x + 1
display dialog "x: " & x

It always displays 3 as the result.

Hi Kaydell,

Yes, it always displays 3, because you redefine x each time the script is run.

Try this version, which defines x only during the first run:

global x

try

x

on error

set x to 2

end

set x to x + 1

display dialog "x: " & x
