I think using isset should do it. try:
for ($i = 0; $i <= $ffromx; $i++) {
if (isset($ffrom.$i)){
echo $ffrom.$i."<BR>";}
}

I have a page with about 80 checkboxes on it. The values are names and
my users are to select names. Now on the next step I want to be able to
list all names processed. I thought a for loop would be best but am
having problems. $ffromx is the number of checkboxes generated in the
previous step. So I want to step through each to make sure that they
were checked or not and then display them.
for ($i = 0; $i <= $ffromx; $i++) {
if ($ffrom.$i){
echo $ffrom.$i."<BR>";}
}
