Two points. The first is that any variable or function used in the last 2
arguments will be evaluated both before and after the tag runs and DE is used
only to quote a variable/function rather than forcing the programmer to do it
themselves.
That being said, the problem is probably in your second argument. Before the
function is processed, the trim function will run and the
Trim(FORM.listing_openhouse) will be replaced with text. If this is 'true' then
the result of the trim will be treated as a variable, not as a value. I'd
rewrite the function as:
IIf(NOT StructKeyExists(FORM, 'listing_openhouse'),
'Trim(FORM.listing_openhouse)', '"N"')
The second argument is escaped and will only be evaluated if it is 'true'. The
third argument is double escaped which is exactly what De would do for you.
This should work for you.
