Change text of GUI button on press

[supraspecies]

I have a button called "Pause" to pause my script. When it is pressed and the script is paused, I want the text of a button to change to "Resume". What function should I use for that?

I tried searching Help file and focums, but couldn't find an exact answer. I assume I need to use some GUI control update function, but I'm a little lost which exactly.

Thanks in advance.
