hi, could someone please tell me the correct way of doing this...

As an example, I have a form with a few variables and a few buttons/labels etc on it. All i want to do is simple things such as on button click, change a variable value then update a label with the new value. Clearly this would be very easy to do by clicking on the button and adding the code directly to the click button event but several people will be working on different button click events so what I need to do is create additional vb files, then on the button click run the code within the additional file (but have the program treat the additional file as though the code was simply written in the button click event area so variables etc can still be accessed).

I'm sure this can be done but have no idea how (being new to this...).

I'm sorry if i have made little sence here, please let me know if you need further explanation. Many thanks to anyone who can help.
