I downloaded timer.dxpack, and I've been trying to modify it to suit my needs, but I'm fairly novice to all this and it's not really working.

In 'timer' you have minutes, seconds, and tenths of seconds, then a button to set minutes, and a stop button.

What I want is a timer with hours, minutes and seconds, and when you click the set button, it first asks you for how many hours, then how many minutes. I've tried editing the code, moving the code about, from 'timer' but it's not really paid off and I've been left with a bit of a mess.

Can anyone help with that at all? A link to a tutorial, or anything like that would be very helpful.

Thanks.
