UNEXPECTED OUTCOMES.

The spreadsheet embebed in my website ( http://www.planfinan.com/home/planificacion-financiera-a-c-p/modelo) has been working properly for months. Nevertheless, currently, it is issuing wrong results. When it comes to changing some data, in fact, cells U16 and T16.
I assume, you have updated something on "ZOHO Sheet" settings, so that, I am not able to find out what's not working accurately.

I hope this information has been of use.

Thanks for helping.

Isidre.
