From: Karl DeSaulniers on 17 Mar 2010 00:07 Hello, I have been asked to see if I can set up an online calculator. I was wondering if anyone had some pointers on where I can lear/find a script that calculates percentages. The regular math part I think I can figure out. Its not a complicated calc, just basic math and percentages calc, a payment calc if you will. TIA Karl DeSaulniers Design Drumm http://designdrumm.com

As for the maths behind it, I'm not sure. -- Postgresql & php tutorials http://www.designmagick.com/
