Hi

I am trying to create a file where I can simulate a bunch of things for a soccer match.

However I am getting a problem: I don't know how I can create a timer to count the time on the match.

What I need it a timer with a start button and stop button.

Then I need to take a stamp each 30 seconds in order to use the time still left to calculate my things on the file.

Is anyone capable of giving me a hand please?

I am using Excel 2007

Many thanks
Dedes
