I have what seems to me to be identical code trying to look at a cell value.

When I'm running my macro in single step debug mode and hover my cursor over this command: 
 If Range("S" & I) = "New Membership Required"  Then
It displays the true value in the appropriate row in column "S" ** I is in for/next loop. This code works as intended.

But I have another piece of code in the same for/next loop that doesn't show the value when I hover the cursor and also doesn't work properly: 

 If Range("D" & I) <> "" Then

I visually see that the cell value does not = "" but the code skips instructions following the "Then".

Both column S and column D are defined as "General".

Thanks for any assistance.
