Calcul Problem Occured on Spreadsheet Doc.

Hello,

My wife and I are Zoho users since novembre 2014, only for family accounting's purpose. We are no geeks at all... We use a spreadsheet on a monthly basis, each time a copy derivating from a template I initially designed. It has worked well to our great satisfaction since then. But now, this time, we encounter a problem I do confess I proved unable to solve :

On this document :

https://docs.zoho.com/file/1go3fd8d79e8a976745b4b076d730ac36626f

Calcul formulas in G43 and G71 are OK. Meanwhile, datas entered for calcul are not taken into account...

I checked my clacul lines, cells formats... I made several new copies from the original template and tried to entered the sames datas, the pb still occured, where it has never done so previously.   

I can't understand it...

Any help welcome

Sincerely,

Ed.
