If you still have an error there, change
if ($num_results = 0)
to
if ($num_results == 0)
See the difference? Realize the error?

Wouldn't you need
if ( $num_results == 0 ) not
if ( $num_results = 0 )
if you do the latter, it will allways be true, because you're setting the
var...
easy mistake to make!
check out comparisons in the manual for more info.

Being relatively new to php, I discovered the following after about 2 hours
of debugging last night and was wondering why???
I had the following code:
if ( $num_results = 0 )
{
echo "no records found";
}
else
{
for ($i=0; $i < $num_results; $i++)
{
