Help with FastReport

Hi,

I need help in my FastReport on how to make the amounts in a column compute automatically (divided by 50) if the item on one of its rows matches the requirement (Registration).

from this:

Amount       Name         Description
100             John           Registration
200             Mary           Meals

to this:

Amount       Name         Description
2                 John           Registration
200             Mary           Meals

Please see attached.

Thanks!
