Hi Federico,

Thanks for the reply. Both of these are of the many I thought of and I prefer option #2 as well. I believe this is the way I'm going to go.

>>I'm working on a form that has several calculated values. Some are based on other values on the form, some are counts of records in related child tables, and some are sums of records in related child tables. I have no problem with the code required, I'm just wondering where is the best place to put the code because I've thought of so many? I'd really appreciate any input on your approaches and any reasons/benefits to why you did it this way. TIA
