Hi Tim.

>I need to be able to programmitically add a field to a report. The field must be the first field in the detail band (it is going to call a function that will effect the other fields in the band).

If this isn't going to be a "real" field (ie. it doesn't display any information) but only used as a function call, you can easily put the call into the OnEntry expression for the detail band, which fires on every record. Find the record in the FRX with OBJTYPE = 9 and OBJCODE = 4, then put the call into the TAG field. That would certainly be easier than trying to add a field at the correct spot.
