Function within IF function

[WalChar17]

I was curious if there is any possible way to run a function within the if function such as: =IF(IS BLANK(G3),"","") but I would like to insert the function =DATEDIF($G3,$M3,"M") in place for value_if_false so if the IF is false it would calculate that formula and display accordingly

? ... just go ahead and position the secondary formula in the value_if_false field :
=IF(ISBLANK(G3),"",DATEDIF($G3,$M3,"M"))

The problem with that is then the cells within the DATEDIF function aren't highlighted for use, they are just a letter and number not active cell.

IF function #NUM!

When I type =IF(ISBLANK(G9),"",DATEDIF($G9,$M9,"M")) It works but when I do =IF(ISBLANK(G10),"",DATEDIF($G10,$M10,"M")) it gives me #NUM ! And I can't figure out why...

Re: IF function #NUM!

What values do you have in the cells?

Re: IF function #NUM!

M10 must be greater than or equal to G10. Check.

M.

@WalChar17.... Try the following instead:

=IF(G10="","",DATEDIF($G10,$M10,"M"))

G10 might appear blank, but its value is actually the null string (""), just like the result of this formula.

Only use ISBLANK when you want to be sure the cell is empty (no value), distinct from merely appearing blank.

PS.... Why do you use G10 in one place, but $G10 in another?
