ERROR: invalid rpn expression in: a,b,+,c,+,d,+,e,+,f,+,g,+,h,+,i,+,j,+1,/

It workd when it was this:

a,b,+,c,+,d,+,e,+,f,+,g,+,h,+,1,/

For 8 items

I'm trying to basically make a "sum" of 10 items, I had it working with 8 entries, but when I tried to make it work with 10...no love

Maybe I'm missing something, but shouldn't you do it as

a,b,c,d,e,f,g,h,i,j,1,+,/

After all, you're just summing all the values together right?

See what I mean. It's been so, I can't even remember how to spell it. We called it "Reverse Polish Notation". I don't know if that's what you really call it though.
