hello, i'm having trouble getting my delete selected checkbox working for a code I'm writing:
the trouble is really just in the bottom half of the code after i make the while loop...i made this off of an example that i found on a site but like it was pretty clear that the site's code had many errors for example...the coder made an input tag and later called it as a $variable which i'm pretty sure isn't possible..anyways some help would be much appreciated :)
