Re: Ajax

Hi Ethan,
With all due respect, I really wish I could help, but your structure  
of how your doing your
html and php and javascript mix doesn't make sense enough for me
to understand what it is your doing or how to help you. I copied and  
pasted your original code
in my editor and it broke all over the place with the syntax  
highlighting I have.
That is a big sign your code is not developed properly. Not even the  
basic HTML.

I'd suggest getting yourself aquatinted with basic HTML structure first,
then continue with any front or back end languages like
learn how to get the value of fields vs. a TD and how to pass them to  
functions.
How to echo php vars into javascript vars, etc.

Got to learn to crawl before you can walk as they say.

:)

GL,
Karl
