I have a form with several text variable fields (30) in which the client is
asked to select and assign a weight to each variables that influenced their
decision to do something. The total weight of all selected variables must
total 100. I have a field "total weight" that I want the sum of the
assigned weights to appear. As the client assigns each weight the total
weight would update using an onChange(or similar action). I do not want the
client to have to click a submit or calculate button in order to have the
total displayed. I want to remain on the same form so that the client can
make alterations to his/her assigned weights until they equal 100.
My web hosting/server provider does not allow any type of sql databasing on
their server so I will be gathering the data in a text file so there is not
interactivity with a database.
Is this such a difficult thing to do, or am I just not seeing the forest for
the trees? I'm befuddled. I've even resorted to learning some java and cgi
scripting to accomplish this but, I now realize, given my time frame, I
don't have time to teach myself all I need to know about these languages to
make this work.
You can view a sample of the web form I have created thus far at

I appreciate any direction you can give.
