Disable check box from a seperate a function

[Muffy1979]

Hi,

I am Completely new to Autoit(24hrs) the last time I did any kind of programing was over 10yrs ago using visual basic, I have got this far by pure and simple luck and hours of research.

Please excuse my lack of correct terminology but I will explain my requirements as best as i can.

I need a GUI that will allow me to check/uncheck a checkbox (Pushlike) then will enable/disable further checkboxes accordingly. I have managed to get this working exactly as I need it but when I place the main body of the script into a function call it no longer works.

I have rewritten a simpler version (below) of exactly what my problem is as my main script is now 2k lines long and is getting a tad complicated.

As you can see if i comment out the function commands it works perfectly but not with them in place as I require.

Because your checkboxes are assigned to variables that are contained in the Function Main(), those variables are given a local scope. That means that they're not accessible from outside that function. You need to declare them as Global, either inside the Main function, or at the top of the script which is the usual practice. Once they are declared as global variables, your script works like I think you're trying to get it to work.

BTW, if you want to call a specific function, you don't need to use the Call function, you can call it like this:

Main()

The only time I would think you'd need to use the Call("Function name") function would be if you're dynamically calling a function by a name contained in a variable that gets changed somewhere along the line.
