Straight Table Summary Total not working

[#1]

Hi,

I have a straight table object with 3 expressions, all of which have the "expression Total Mode" selected but I the total row shows ' - ' for all columns. Any ideas?

Thnx

Are there any null values? Which are your dimensions?

No nulls. I'm using Month as dimension.
