Well it looks like 'Add to Shopping Cart' is a link. The 'webpage' it points to is: javascriptlace('Orange Cap'). (found in the href attribute...).

Now that looks somewhat bizarre right off the bat. So now that leads us to believe that your friend is trying to execute some Javascript, possibly trying to make a Javascript function call? Now what's the name of this function?

Is it: javascriptlace or lace?

In the href attribute, to make a Javascript call, you need to use the following prefix:
javascript:xxx(...)

<a href="javascript:lace('Orange Cap')" align="left">Add to Shopping Cart</a>


The alternative method is to do the following:

<a href="#" onclick="lace('Orange Cap');" align="left">Add to Shopping Cart</a>


Either way, after studying the provided code, there were no functions found. You have to create the function (whether it's javascriptlace or lace) before you can make a call to it.

Hopefully that helps, post back if you're still having problems. Also, wrap any and all code in [ code ][ /code ] tags (no spaces) and ensure proper indenting is applied (for our ease of reading..)

It had to be place and not lace.

He has almost completed his shopping cart program.

Thanx for the tip on the [code] tags!

Thank You for your trouble and sorry about not using code tags

Cheers
