Thanks for the quick response. That does give me a little more clarity
but I guess my question was how do I define my variable with a value
that is in params? When I do alert($("#params")) I get a response of
object Object. When I do alert($(form.serialize())), I seem to get
most of the params values except for the one that I want. It also
doesn't look like its in an array so I can't chose the element that I
want. Granted I am new to jquery and don't fully understand
serialization and a great many other things. I believe the first alert
is telling me that I can get to the entire params object using an id
of params. But how do I get to the value within it to be able to
specify my data variable in my $.ajax() statement? Sorry If I am not
making much sense...
