Hello guys.

This is the most difficult JavaScript problem I've faced so far, but I have to get through it. It's a sample shopping cart. It's also very long so I'll just ask questions piece by piece.

For now, I would like to know why my function that's suppose to add dependent 'options' to a select tag isn't working...

Here's the site: http://www.ibtestsite.info/purchasepage.html

There is a 'sock' item and a 'polish' item. There are two kinds you can select for each, and with each selection there are two types that are suppose to appear in the adjacent blank 'select' tag to each item. Any suggestion is appreciated. Attached is the JavaScript file.

Please ignore the HTML coding..I did it in about 45 mins (which is a record for me ) and I don't care what it looks like in IE right now. Please view in Firefox/Mozilla. Thanks.

I get 2 different errors when I change the value of a select menu.

Error: sub_sel1 is null
File: http://www.ibtestsite.info/javascript/shopping_cart(sample_c).js
Line: 118

for the first

and

Error: addPolishOpts is not defined
File: http://www.ibtestsite.info/javascript/shopping_cart(sample_c).js
Line: 26

for the second.
I don't really feel like working myself through ~150 lines of code at the moment, though.

This is an issue as well..as I continue to correct things through 'error console', I don't understand why the above is 'null'....but hopefully I'll find out why as I continue to play around with the code.

If ever you get time to advise further, it would be appreciated.
