Well, it won't if those variables aren't structs. ;-) But luckily practically everything in CFML is a struct. > Basically, some of the instances where #index# will be used is in the > name of a query variable. > > aka. > > myquery_1.my_column > > = > > myquery_#index#.my_column > This wouldn't involve StructKeyExists anyway. If that's the only way to do what you want, you'd have to use Evaluate(). StructKeyExists() would be used if you wanted to see if my_column existed in your query, but not inline on the actual query name like you're trying to do there. Bit of an aside, but queries (and most other CFML datatypes) can be treated as structs, so you can do things like myQuery.myColumn[rownumber] or myQuery[myColumn][rownumber] to get at query data in different ways. But if the actual *name* of the query is dynamic, you'd have to use Evaluate() or come up with a different way of accomplishing what you're trying to do. As far as the form scope goes, remember you can use bracket notation there too: form[variablehere] form["dynamic_#stuff#_here"] That lets you throw variables into the mix in ways that aren't possible with dot notation. -- Matthew Woodward [email protected] http://mpwoodward.posterous.com identi.ca/Twitter: @mpwoodward Please do not send me proprietary file formats such as Word, PowerPoint, etc. as attachments. http://www.gnu.org/philosophy/no-word-attachments.html
