returning values from a multiple select field

Hi all, Sorry to post this question, but I cannot access the php.net web site. Also could you reply to my email address, thanks. I have a multiple select field, how can I retrieve all the values selected? i.e. <select name=tripselect multiple> <option value=value1>Value 1</option> <option value=value2>Value 2</option> <option value=value3>Value 3</option> </select> I get the variable tripselect in my new form, but I can't find out the correct way in which to find out all the values of tripselect. Any help? Again I apologise as I would have normally used the web site, but it seems to be down. Thanks Sam Rose
