Thanks so much for your help Bob,

I have modified your code to add protection and a helpful message box so
it's all working beautifully.

Thanks again

Hi

I am totally new to VBA and really need to do some help!

I am writing an excel worksheet to send to students practising for multi
choice exams. They are supposed to press a button when they start the paper
which will then record the start time in a box. I have written a macro that
does this and protects the cell so that the time cannot then be changed but I
want it to automatically run if they answer any questions without pressing
the start button.

My idea for doing this is to use the worksheet_change function to watch the
cells into which the answers would go (namely C12:F37) and if any of those
are changed run the starttime macro.

Can anyone tell me how to do this or give me some code that would work.

Many Thanks

Jonathan
