[support] db_num_rows(db_query(...)) issue

[Kobus Myburgh]

Thanks a lot, Merlin! :-)

Yup, as I thought... I did something stupid. It makes PERFECT sense now.

Okay - my percentage counter is now working  at www.drupal.co.za :-)

Thanks again!

Kobus

The COUNT query returns 1 row with 1 column. That column is the count.

You want to use db_result, not db_num_rows.
