sumif multiple criteria on different sheet

Hi,

I hope someone out there is able to help me with this problem. I have been trying for hours with no avail.

On the TOTALS sheet I need to sum up the values matching up with two criteria items CODE1 and CODE2 for which the values to these are in the RAW DATA tab.

I have tried SUMIF and SUMPRODUCT, but I cant seem to get it to work.

Thanks to anyone who can help me.
