               [B]if (check_one_select()==false) {
			mid.focus();
			return false;
		}[/B]
	}
}

the remaining code execute except the bold one...the problem is in the check_one_select().can u please help me to solve this problem

Check line 81:

<td width="50%">MotherBoard ID:</td>
<td><input id="input3" type="text" name=""mbid/></td>
="text" name=""mbid/>

should be

="text" name="mbid" />

I don't know Jquery or JS really, but I'd put a bet on that quote being the problem.

That's the first thing I noticed as well...

<input id="input3" type="text" name=""mbid/></td>
//needs to be fixed 
//name="mbid";
// I ran the code it all seems to function just fine as long as the mbid is fixed.

thanks to all of u.it worked...
