Hello. I can't understand what's wrong, aggregate functions don't work, it gives the same error all the time. Already tried different options with different databases and hosting. Please suggest what could be the problem. Here is an error screen: http://snag.gy/GdDHj.jpg

Thank you.

    Try to remove the space between SUM and the bracket (). It should turn out like this: SUM (), but not as it is now SUM_ ()
