I'm new to Gambas (but have experience of other programming languages) and have just started experimenting with it. I've written a simple piece of code with a main class FMain that creates two buttons hButton1 and hButton2, and I'm trying to use the hButton1_Click event handler to change one of the attributes of hButton2. However, when I try to run it I keep getting the error "Unknown identifier: hButton2 (FMain.class:34) within the event handler. I assume this means that hButton2 is out of scope within sub hButton1_Click but can't find any information on how to fix this. I am running Gambas from Linux Mint on a desktop PC.

It is always a good rule to show the part of code that produces the error.

Uhmmm… did you formally declare hButton2 as "<COLOR color="#800000">Global</COLOR> " ?

Thank you. I understand now. I was basing my code on an example program in which all the variable declarations were inside the form_open subroutine, and was under the impression that this made them global by default.
