Re: Invalid argument supplied for foreach() , when i use sessions

cricket..thx for your help...the loop was empty as far as i could
tell...works now :)

i appreciate it.......

but i have sth else making me nuts.

when i echo data, it automatically makes a break with <p> and prints
the text into the next line...so my echo code is this in html:
<span class="data"><p>desc</p></span>

how can i make this <p> go away? cause my text wont appear where i
want it to be...i wanna print text without making a break
