That gives the following error which is the isset line:

Parse error: parse error, expecting `','' or `')''

I think using isset should do it.  try:

for ($i = 0; $i <= $ffromx; $i++) {
   if (isset($ffrom.$i)){
       echo $ffrom.$i."<BR>";}

Subject: [PHP] Running for loop and concat. variables...

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>";}
