Hey everyone! I've written a short PHP script that calculates a result from two input values. The working calculator can be found here: thepokerbank.com/strategy/basic/starting-hand-selection/chen-formula/ However, I think this type of calculator would work much better as a client side script than a server side one. I'd be happy to pay anyone who would be able to convert this PHP script to a Javascript one (or just to write a Javascript one from scratch - whatever is easiest). Here's a link to a txt file of the current working PHP script and the form: thepokerbank.com/chen.txt Send me a PM with a quote price if you'd like to have a go at wiring a JS script for this short calculator. Thanks!
