No, if you allow user entry to a cell containing a formula, the entry
will overwrite the formula. You could allow data entry into another
cell, and have your IF formula pick the data from there in the false
clause.

Here's an example:

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

This checks B1 to see if it is not blank and if so it will return the
value from there (User entry), otherwise it will pick up the value
from A1.

Hope this helps.

Thank you for the help...I appreciate it.
