Calling a flash function

I’ve never gotten the flash command “call function” to work reliably. However, set variable seems to work a lot better. So I create a variable in flash and set it to 0. Then I create an onEnterFrame to watch that variable and call a function if it changes. It looks something like this:

Then on the lectora buttons onClick I use set variable --> callFunction --> and I set it to 1. Hope that helps.
