Two Variables in Dynamic Update….

Nov 03.2005

I have a n00b question here. I am working on a page that will accept values from a text box (an integer) and a drop down menu (integers 1-25). Without submitting the form, I want to be able to calculate the text box / drop down menu.

I have no idea how to do this. Dynamically updating 1 variable is easy, but for the life of me, I can’t figure out what I’m doing wrong. Any assistance would be greatly appreciated.

Mike

Add 'parseInt(value)' to your javascript.

Success!
