Message Box keeps on popping up

Hello,

I have included in my VBA a line that reads:
MsgBox "Available from 1 to 150 MHz"
whenever there is an frequency entry (column M) in that is lower than 1 or higher than 150.

However, the message box just keeps on popping up, even when the frequency section is empty. You will see what I mean when you click on the drop down list in the attached file.

I even added a case: Not IsEmpty (Cell M). Please tell me how I can fix this bug.

Thanks,
Juju

You could try this approach.

test it being between 1 and 150. if so do nothing

if not, test for blank
if blank do nothing
else delete (say for 200, or 0.5 etc) and provide the message

Cheers

Case 1 < Range("M" & x).Value < 150
        Case Else
            If Not IsEmpty(Range("M" & x).Value) Then
                Range("M" & x).Value = ""
                MsgBox "Available from 1 to 150 MHz"
            End If
            'Limited frequency range for P4 (1 to 150 MHz)
        End Select

Hi Brettdj and Saurabh,

I have tried following your approach, but when testing (type in 100), the message box came up. Did I misunderstand your code?
