I guess you want to do this    total rating count   count  total rating count   if   total rating count  gt  0     because you can t divide through zero     avg   round  total rating points    total rating count  1

I had a similar error with the following code -  foreach  myvar as  key   gt   value        query    SELECT stuff             FROM table             WHERE col1     criteria1              AND col2     criteria2          result   mysql query  query  or die  Could not execute query -   mysql error      FILE      LINE     query                       point values   mysql fetch assoc  result        top five actions  key      point values     lt --- Problem Line            It turned out that my  point values variable was occasionally returning false which caused the problem so I fixed it by wrapping it in mysql num rows check -  if mysql num rows  result   gt  0             point values   mysql fetch assoc  result            top five actions  key      point values      Not sure if this helps though   Cheers
