This is for a test so here is my example:

I created a pivot data chart and the items were:

drum
guitar
keyboard

followed by the months of the year

I dropped the months in the series field and that was fine. I then took
drum, guitar and keyboard and it reads "sum of guitars" "sum of keyboards"
"sum of drums".

I don't want the "sum of" to appear ..I just want "guitars" "keyboards"
"drums".

Thank you.
