Loading vars help

I dunno if 'm posting in the right zone still… i did a typical loadvars only i did it on the onenterframe event… and it loads one million times the same thing… so i modified it to load only when it changes… and it worked… if i changed it manually from notepad then the text from flash changed… So i decided to go even furtherer and thought of modyfing the text file in flash using php… i sent the variables to php… the php script modifies the text file but the flash program doesn’t… why?? I REPEAT… only when using php… manual edit works…
