Need VBA to create a clock/timer

Hi,

Thanks in advance to all for looking and trying to assist me with my problem.

I need VBA to create a timer in mm:ss format which would start by pressing a "Start" button, pause by pressing the "pause" button, and Stop by pressing the stop button. Now when the user presses stop the last time should be saved in sheet(2) of the worksheet(next worksheet).

I am actually trying to calculate the total time spent while making an entry in the spreadsheet. The user might toggle between various activities, but i need to find the net time spent on this activity.

I would really appreciate any support for the above problem. I am in the phase of learning VBA.

Thanks a ton.
