Solved this puzzle (though it may not be the best example of code
writing) and thought I'd put the solution here in hopes of helping
someone else in a similar bind.. :-)

if ((($status == "Complete") or ($status == "Resolved") and ($datecomp
== "")))
{
echo 'All items marked COMPLETE or RESOLVED must have a date
entered. '
.'Please click the browser BACK button, fill in the date and
try again.';
exit;
}

if (!$datecomp && ($status == 'Complete' || $status == 'Resolved'))

....use '=' for assignment and '==' for comparison.

The variable passed to PHP is $_GET['datecomp'] or $_POST['datecomp'],
not $datecomp. (register_globa ls is evil and should be turned off).

There's no meaning to a subexpression like: "Complete" or "Resolved".
Think of it as: If status is Complete or status is Resolved, then ....

if (isset($_GET['datecomp'] && ($_GET['status'] == "Complete" || $_GET['status'] == "Resolved") )

{
echo 'You must enter a DATE for items marked Complete or
>Resolved. '
.'Please click the browser BACK button, fill in a Complete/
>Resolved date and try again.';
