hi,
yes, you need to define a global variable for this purpose.

I tend to use package variables for that. :GLOBALs are more useful across forms. So my answer would be: "no you don't have to, but that 's one way of doing it."

But he didn't mention that he's using a package variable.

Quote:

This statement shows that he has defined a local variable inside a form trigger which cannot be used outside in any other trigger unless he changes this local variable to a global variable or as you suggested a variable inside a package.

He can also create a package in his form and either (I can't remember which works in which version of Forms) declare that variable in the 'spec' of the package OR declare is in the body and use functions to write and read it.
