Custom formula to allow only numeric entries in a range.


I am trying to write a custom formula to allow only numeric entries in the cell range of E4:E10, E13:E17. I entered the formula below in Data Validation & received a error message saying "A named range you specified can not be found." What am I doing wrong? When asked if I wanted to "apply these settings to all other cells with the same settings", I checked the box. If I did not follow the rules regarding posting formulas, let me know how to post formulas.
