Simplify Formula

[cyliyu]

Need some advise.
Can I simplify the following formula?

=IF(E4="","",(IF(F4="","",(IF(T4="","",IF(T4="∞","",(IF(T4>=180,"Yes",""))))))))

1) Check if column E4 and F4 are empty, If they are, return a blank space. then
2) Check if column T4 is not empty and not infinity, if it is, return a blank space too. else
3) perform the last If statement.

This I'm almost certain this will do it:

=IF(OR(E4="",F4="",T4="",T4="∞"),"",IF(T4>=180,"Yes",""))

but you could also test:

=IF(OR(E4="",F4="",T4="",T4="∞",T4<180),"","Yes")

Thanks, P45cal.
Both formula works.
Appreciate your help.
