>>>I've created a container class with a timer and a command button group in it, when the timer (timer1) fires it clicks the first command button (command1) and shuts itself off like this:
>>>

>>>this.parent.commandgrp.command1.click
>>>this.enabled=.f.
>>>

>>>Which starts a process that cascades through the command button group. All this is working fine, the problem comes when the last command button attempts to restart the timer with :
>>>

>>>this.parent.parent.timer1.enabled=.t.

>>>The timer is not restarting, is parent.parent a valid reference ? Is their any other way to reference timer1 from a button in the command button group ? Should I just give up on finding something useful to do with command button groups ?

Your code ran cascades of button clicks, enable timer there, then returned to the timer.timer snippet and disabled timer. VFP fires commands in strict sequence (at least theoretically).
