I would appreciate help with this problem of Excel reporting that it has run out of resources and so cannot evaluate my formulas.

I thought it may have been that the spreadsheet was too busy, so I copied just the first sheet and removed as much of the non-required info, (reducing from 23MB to 7.3MB) but still the problem remains. I have removed the conditional formatting.

I am running Excel 2013, W8.1, in a 16GB RAM, i7-4800MQ at 2.7GHz, so I cannot fathom what limitation I am hitting.

In the attached spreadsheet, the troublesome formulas are in B2802 - B2854, & C2802 - C2854. The problem first came up when I copied across from the B col to the C col.

I tried to get a link to my OneDrive, but I'm afraid it defeated me. I hope this link with MediaFire will do.
