I disagree. This is what you call the copy and paste technique... the code is now double the ugliness, a nicer solution would take a little more typing. But a little less total code.

The use of the element name (to locate dom elements) isn't really supported across browsers, it works now in Firefox, because most pages are written for IE. But I don't know how supported it is across other browsers.

Cheers.

That's cool, I get bored at work. as a rule of thumb, the easier it is for people to access the problem, the easier it is for them to help.

If I can glance at the code and see I can paste it into a webpage without editing it, I will, even if I have no idea what the problem is! So what you did with a zip was handy, as the images are rather important sometimes too.

Everything you have mentioned is doable, as always, a problem has many solutions.

Have fun.

alpha_foobar,

I hate to beat a dead horse, but...

I created rater2 with mouseover rather than mouse drag. Do you think this will work too? I only found one problem. If you mouseover and click on one of the numberes, then mouse over the link to display the rating, it will display the javascript alert twice. If I used
<input type='hidden' name='rate' value='"+rate+"'> do you think it will cause an issue with double votes like the javascript alert has?

Thanks,
