accessing dynamic var

in a form i use this code

// $numbOpt is set else where for this lets say $numbOpt = 5
$num=0;
while($num < $numbOpt) {
$num++;
print'
input name="opt$num" type="text">';
}      

in the next page is use this code which doesn't work

while($numbOpt > 0){
$Opt = "$opt".$numbOpt;
$query = "insert into PollOptions"
." ( `id` , `Qnumb` , `option` ) values "
."('','$Qid','$Opt')";
mysql_query($query);              
$numbOpt--;
}  

does anyone know how to do this, i can't figure it out. thanks
