Eliminate some inputs

[YA_10963798]

Hi there, 

we have so many inputs I need to write a program to tell mathcad , if the input matrix or table has less than 700 rows don't include it in the calculation. Can you help me doing this , please? The sheet is attached . 

For example I don't want Mathcad to do the calculation for CPT3 because it has less rows than 700

Seems that only two of your six matrices qualify.

Thank youuuuuuuuuuuuuu soooooooooooooooooooo much 

What does (Nan) mean? is it constant or variable?

NaN ("Not-a-Number")is a predefined constant.

Its the result you get if none of the matrices qualify because they all have less than 700 rows.
