Basic Syntax Problem

[Guest]

Can anyone please tell me what is wrong the following syntax in an unbound
text box inside a report or suggest a better method?

iif([Forms![Date Input Form]![Desired Date],"Forms![Date Input
Form]![Desired Date], "Forms![Date Input Form]![Begin Date] & ' until ' &
Forms![Date Input Form]![End Date]")

I get an error that says
"Syntaz error (missing operator) in query expression
'First([iif[Forms]![Date Input Form]![[Desired Date],"Forms]![Date Input
Form![[Desired Date], "Forms]![Date Input Form]![[Begin Date] & ' until ' &
Forms]![Date Input Form]![[End Date]")])'

Basically all I want it to do is either print out a single date, if
available, or just a string concatinating 2 dates and the word 'until'
between them. Is there an easier way to do this than what I'm doing?

Thanks,
Keith

The first argument in an IIF statement has to be an expression. Try changing
it to this:

iif([Forms![Date Input Form]![Desired Date] Is Not Null,Forms![Date Input
Form]![Desired Date], Forms![Date Input Form]![Begin Date] & " until " &
Forms![Date Input Form]![End Date])

Adding the "Is Not Null" got rid of the syntax error, but now I just get a
#name. I thought it might need quotations around the if-true and if-false
statements, but I'm apperently not getting the right combinations, especially
with the trying to add in the 'until' part. Any ideas?
