that alright it's been a pleasure. In fact I'll probably do it anyway just for the fun of it

Nevermind, we decided to just take out the calculators. Thanks so much for your help anyway

Don't worry about it - it was good of you to do that much already

if you can wait until monday i'll probably find an answer but i' a bit busy now sorry

That seems to work! Thanks a lot!

But, another problem - an error occurs when the user tries to put in more than one operator (i.e. 9+*). Any way to fix that too? I'm trying to figure out what you did there but it's a little bit beyond me I've tried looking for a different script but I can't seem to find one with the xy function. I might just decide to take out the calculator (seeing as how the users probably have a real one sitting on their desks anyway).

try this it should work but i didn't test it

function calcit() {
strExp = document.calc.shownum.value;
intopen =0;
intclose=0;
for(i=0;i<strExp.length;i++)
{
   if(strExp.charAt(i)=='(')
   {
       intopen++;
   }
   else
   {
      if(strExp.charAt(i)==')')
      {
         intclose++;
      }
   }
}

if(intclose!=intopen)
{
document.calc.shownum.value ="error";
return;
}
		   if (document.calc.exp.value == "x") {
			document.calc.shownum.value = eval(document.calc.shownum.value);
		   }
		   else {
			document.calc.shownum.value = eval('Math.pow(' + document.calc.exp.value + ',' + document.calc.shownum.value + ')');
			document.calc.exp.value = "x";
		   }
		}
