pick is being used as an array in your form but I think the test is
looking at it as a regular variable which isset is most likely always
evaluating as true.

You can test if each element in the array is set isset($pick[0]) etc
but I don't think testing on the name of the array will give you what
you want.

You will need to iterate through the array testing each value.

An excellent place for info on php is http://www.php.net.  They have
have a lot of good examples and you can search for information on
various functions very easily.
