WGM, as I see it there are 2 choices - a where clause (without the word Where) and a zls.
I cannot figure out how to get the frmAccountReport
I guess sfrmAccountOther is your subform control? Then you don't need to - it is referenced by the word Form, as in sfrmAccountOther.Form
Are you getting a parameter prompt for TransDate, or the beginning or ending dates?
My guess is that you're using an option group to make clause choices for a sql statement. If you fix the parameter prompt I don't see how you can use "" as a criteria option for dates, unless maybe your dates are really strings.
The more we hear silence, the more we begin to think about our value in this universe.
