Re: Using Iif and De together...
IIf(StructKeyExists(FORM, listing_openhouse), 'Trim(FORM.listing_openhouse)', 'N') *should* do it :) On 07/12/06, Andy Matthews [EMAIL PROTECTED] wrote: I KNOW that I've used this method successfully before, but for some reason it's not working correctly now.

Re: Using Iif and De together...
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.

RE: Using Iif and De together...
I think that's what I was missing guys. The extra set of quotes on the final argument.

RE: Using Iif and De together...
Couldnt you just use: cfparam name=form.listing_openhouse default=N / If it already exists, its value will be in form.listing_openhouse If it DOES not exist, it will be created and the value N will be stored in it. ..:.:.:.:.:.:.:.:.:.:.:.
