Using =SUM...just can't figure this simple thing out...

Hey everyone,

I'm trying to get this formula to work. It seems very simple, but it'
just not working for me. Someone here can probably see what's wron
right away...

=SUM(((J6:J8,J10,J15:J25)*((B29/100)+1))+J11:J13,J26)

I'm trying to add the cells (J6:J8,J10,J15:J25) together, and then tha
total needs to be multiplied by (B29/100 and then add 1). Then whe
that's all done, add the cells J11:J13,J26 to the total.

Any ideas? Would be greatly appreciated.

Thank
