Formulas giving unexpected errors

Hey all,

A while back you guys helped me start a spread sheet for work, in which I'm still eternally grateful!

Now, I've added a few things to fine tune it to how I need it to work. But, I'm hoping that one of you gurus will look it over and dot the i's and such.

I'm getting a few small errors. In particular is the area of R/T 3-8. And F25.

I really appreciate all you guys help more than you can possibly know.

Thank you!

In R5 instead of
=T3+T4

use
= Sum(T3,T4)

if R5 is not giving error, then F25 is also not giving error.

did you make any changes to the file, formula ?
if so pls upload new file.

Nvm, false alarm. I was looking at an old version of the sheet on my tablet.

But now, when I try to select N19 on the tablet, it says something like "unable to edit array."
