1 - If you need this kind of customisation, make you own userform instead of
using the Inputbox.

2 - You are currently using <IsEmpty(cell.Value) = "", which seems like a
mix of the 2 similar statements:
IsEmpty(cell.Value) = True
cell.Value = ""

Use one of these

This code works(!), but does not do everything I'd like it to do.

1. When it finds a cell , I can click "cancel" to ignore the cell and go
to
the next one. This is great, because many times the user will want to
leave
the cell as is, but I would like for the cancel button to say "ignore" and
to
have a "real" cancel button to exit out of the macro. This may be too much
to
ask for, but putting it out there just in case.

2. It seems to find cells with letters, symbols and spaces, but it's not
finding blanks.
Column 1 should contain only a number (positive number).
I'd like to find cells in the first column that:
a) contain any letters, symbols or other non-numeric characters
b) contain a space
c) are blank

Hope there's someone out there who can help me out.
Thanks.
