If you want to set value to a field, then use replace command, or gather.

You're setting the variable needDmr to .t., but displaying a value of the field (field always takes precedence over the variable). If you want to check variable's value, use m.needDmr

m. was one of the sore points at one of my previous jobs <g>

>Ok, I think we've just been looking at this thing for so long. In a larger code, we fixed many other errors and seem to have it all working but this one line. We are simply trying to set this field to True or False once everything else has been done. However, the field (needdmr) stays false regardless of what we tell it to do.
