yes. define your variables at the top of your code as globals. I t will look a bit like this:

If you mean you've declared it global and it still doesn't seem to be recognized in your function, check the spelling of the variable name. A typo means you're looking at the wrong variable.

just create the variable at the top of the code like this:



It doesn't matter what you do with it in your program, just set it as global at the top and the function will be able to access it.

I'd been wondering what globals were - saw them in a snippet but couldn't find them in the help files. Stupid help files...

So a global variable is just one that can be accessed (read and altered) by functions?
