You know I was thinking to check it against one of my pre determined values and was going to use in_array() to search for the value. I read somewhere that if there's a select box in a form and it gets submitted, you receive the value as an array? Did some var_dump()ing and it showed up as a string so I'm not sure how true that was. I have already created an array in a script dealing with my products page so I wonder if I can use that value in this script or whether or not to just create another one.
EDIT: just found it. inside the same file. moved it about and its got global scope now.
Thanks for the tip.
