Re: FileExists using variable - not working
To troubleshoot, one, the pounds are not needed so I'd take those out. Two, in cfelse, what is the value of: cfoutput#variables.ImageSource#cfoutput do something else In other words, what is the variable's value as soon as you hit cfelse. - Gabriel On Thu, Apr 8, 2010 at 1:03 PM, Fred Grainger i...@fredgrainger.com wrote: Ok - I'm about to pull my hair out.

Took the hash marks out. Put quotes, trimmed the variable, checked the length of the file name to make sure there weren't any control characters or anything. My code is very straight forward. A day and a half later, still no dice. This is the first time I've used this function. We just upgraded to CF9 a few weeks ago, but it is up to date. This makes no sense whatsoever.

Re: FileExists using variable - not working
Yep - If it type in a literal into the variable it is working. When I build the file path from the database fields it will not work. When I manually cut and paste the cfoutput of the variable I build with the database fileds into the fileexists function it finds it. It does not like something about the variable that is created with the query value. I'm sure it is something simple. I'm about to throw in the towel though. I cannot get this to work.

So I took their example and fixed it so it would work.
