# Isnumber

You gave me the formula below which works fine for the populated rows.

IF(D17="","",IF(ISNUMBER(SEARCH("Terminal",D17)),"Term",IF(ISNUMBER(SEARCH("Wire",D17)),"Wire","Other")))

However, the unused rows have this in the reference cell:
=CHANGE MATRIX '!E27
This is returning "Other" on all the unused rows. So, in the example above D17 is not really empty.

I need the unused cells to remain empty of "Term", "Wire" or "Other"

### Excel Facts

Square and cube roots
The =SQRT(25) is a square root. For a cube root, use =125^(1/3). For a fourth root, use =625^(1/4).

What value is returned in the "unused rows"?

The formula you already have isn't testing for an "empty" cell, but is testing for a cell that does not contain a value - that way a truly empty cell, or a cell that contains the null character "", will return the proper statement.

Who gave you this formula? If this is a follow-up on a question you already asked, you should post it back to the original question. That way, those who were helping you with this can see it and respond.

No value is returned in the unused rows unless a previous tab is populated.
The cell appears empty but in reality has the ='CHANGE MATRIX '!E13 formula in it.
