Need correct IF(ISBLANK) formula when referencing whether one of twocells (OR) is blank, returning "

[insitedge]

=IF(ISBLANK(A1),IF(ISBLANK(B1),"",C1(likely wron formula);

Don't know if I use a comma or OR, or another formula, but if either
A1 or B1 is blank, I want "no value" in C1. If both A1 and B1 have
value then it returns the Value in C1.

=IF(OR(A1="",B1=""),"",C1)

It would work if you add an OR in there:
=IF(OR(ISBLANK(A1),ISBLANK(B1)),"",C1)
but it cannot both put a value in C1 (ie, live there) and check the
value in C1.

Try this:

=IF(OR(ISBLANK(A1),ISBLANK(B1)),"",C1)

Good Luck.
