Strange problem in for loop

programming flash
1

i am receiving a value from a remote ASP (REG) … this value is passed to a “bots” and i can write and view it in a text field (“mensa”) but when i try to use this value in a for loop i got a script error when testing the movie via F12.

bots = Number(_parent.REG)-1; // number of buttons
mensa.text=bots;
for (x=0;x<=bots;++x){
mensa.text=x;
}

ah i almost forgot … the REG variable got the value from a “eval” instruction … does it have something to do with this problem ? … please help

rgc=eval("_parent.Recibo.RG"+SBS[x]);
mc.submenu.REG=parseInt(rgc);

regards
