How to evaluate a blank field
 

I need to increment a number if the name field is blank but not if there is a
name already entered. The name field is defined as a 'general' field. I
thought I was on to something with a previous post regarding the IsNull
function (Thanks SusanV). However, it appears I'm getting a true result on
the IsNull test regardless of whether there is data in the field or not.

I've written the code as (D8 is the name field):

If IsNull(D8) Then
Code to increment the number and save goes here

But even when the name is blank (tested with a MsgBox) it's still not
performing the code.

Any help is greatly appreciated.

Maybe...

if isempty(worksheets("Sheet99").range("D8")) then
...

Thanks Dave but that doesn't work either. For some reason, even when the
field is empty I'm getting a false return on the isempty function....

Then the cell isn't really empty.

It could look empty for a few reasons:
1. The user hit the space bar instead of the delete key to "clear" the contents
of the cell.

2. You could have had a formula that evaluated to "" (=if(a1="","",a1) and then
converted to values.

Each of these leaves the cell non-empty.

maybe just looking at the .value would be sufficient:

if trim(worksheets("sheet99").range("d8").value) = "" then
.....

You can test for an empty string or use the IsEmpty function.


Debug.Print Range("A1").Value = ""
Debug.Print IsEmpty(Range("A1"))
