292774 Flash/php programer

Hello, i have a webcam chat site and have developed a script for webcamchat in flash and php with mysql as database., We now have some problems that we arent able to solve ourselfs so we need help from someone thats skilled in flash/php/mysql The problems are as followed compability problems with flash in IE, the amounts in members virtual wallet dosent math up. If the member have 29.95 in his virtual wallet then in the flash webcamchat script he gort 0,2995 in IE And then in Firefox it works almost perfect, then the virtual walelt show 29.90 in the script, but when your paying by minute it draws the minute price *100 instead. Another thing is that in the flash webcam script we have added a microphone on/off button but that dosent work so we need that fixed to. So i think that for a good flash/php programmer this is a easy fix, but i cant do it so please help me out here :)
