Could be could of things:

The arrays you reference ($company, $job_company) are global? Depending on your php configuration the globals might not be visible inside a function unless you declare them as globals in it.

Also, you never gave $converted an initial value. set it to "" at the top of the function (where you should've declared the globals...).

In future you should tell us what happens, not just that such and such doesnt happen. If nothing is being printed at all I would say that problebley you are not making it into the loop. Try remove the if($how_many_jobs != "") statement and putting an echo $i; line in the loop to make sure its running.

But now that I write this I noticed that you didn't create a <form> </form> container for these input forms. I'm also not sure if this line: $company[$i] = "$job_company[$i]"; is doing what you think it is. In PHP you dont need to cast to string and you put the " marks around the vairable in your $convert string.
