You would have to set up a Worksheet_Change macro so that when the adjacent
cell is changed, validation is set up. Hard to explain further without
details.

Example:

If Range("B1") = 0 Then
Range("A1").Validation.Delete
Else
Range("A1").Validation.Add Type:=xlValidateList, Formula1:="1,2,3"
End If

I have a Cell that I would like to setup to us an IF statement or a
variable.
I am trying to set this cell up that IF True it will work from a List Box,
but if False it will allow me to type in General Text or numbers. I can
set
it up for one or the other currently, but need it to do both depending on
what is in the cell next to it.
