Calendar Woes With Form Variables | Newbie | | Join Date: Sep 2008

I'm working on a calendar that works well in all points except one. I found the code online and modified it to fit my needs. One of my mods isn't working. I'm trying to make it display the chosen month under the drop down box but I'm getting and "Element MONTH_VAL is undefined in FORM" error. It seems to be defined to me but I could be missing something obvious. I'm using cfif's to look for form.month_val which is an integer and then display the month based on which month has been chosen. That's where the error is. I've noted the section that's erroring out in the comments.
I would appreciate any help. Thanks much. -

Put "form.month_val" in quotes in isDefined(). You could also use cfparam to give form variables default values. There's some code that could be improved, but we can deal with that later.

Pleased to see that it's working, though the displaying of the month and year code looks terribly inefficient. Rather than those if statements, just display the value using cfoutput. For the month, set the option values to the name of the month.
