Hey guys. I was just wondering and hoping, i am very new to html, i'm just getting the basics down. Could somebody help me with a one rep max calculater. On my site i have it in a chart form in the rountines page. What i would like is somebody to enter a weight and then enter max reps preformed with that weight and then it gives you their one rep max weight? I hope thats not to confusing. So if there are any HTML GODS out there can you please give me a hand.

Thank you
