When using a select combo box that has multiple selections enabled, my server was not seeing it as an array. It was only seeing it as a single variable value. All I did to correct this was add [] and the end of the name attribute.
Ex. [code]<select name="categories[]" id="categories" multiple="multiple" size="4">[/code] Now my LAMP server sees this variable as an array in the $_REQUEST Dunno if this is supposed to work like this. Thank you. ~ Shawn
