Division by Zero in Table

[tkupfer]

Hi,
I try to do some calculations with values stored in a table.
In general the calculation works fine until I have no division by zero in may calculation, then I got error message that calculation includes division by zero or only one value is displayed.
In attachments you can see some examples (calculation of SFF).
Thanks in advance for your help.
