Formatting Date

[pschoen]

I have a line in my report to keep the From and To Dates from showing if the
From Date is null: =IIf([FromDate1] Is Null Or [ToDate1] Is
Null,Null,[FromDate1] & " to " & [ToDate1])

My question is, how do I include instructions for mmyyyy formatting in this
line?

Thanks
Phil
