Hi Dana

Thanks for drawing my attention to that. I had not realised it returned
0 length.
Equally, =CODE(A1) returns #VALUE.

Just 2 cents. If A1 just has an apostrophe '
=ISBLANK(A1) returns False, but
=LEN(A1) returns 0.

Hi Bill

Try
=LEN(CD15)
If it is 0, then there is nothing in the cell. If greater than 0,
then there is something there.
If you use
=CODE(CD15)
then if it contains a space it will return 32, or the ascii code for
the character that is there.
It will return #VALUE if the cell is empty.

How do I find out if I have invisible characters?

If you have a formula in CD15 then it is not blank and Excel will
return
FALSE

Try this instead

=IF(Sheet1!CD15="","",Sheet1!BU6)


If you don't have a formula in CD15 then you must have invisible
characters
in the cell

I am using ISBLANK in a formula and it keeps returning "false"
when it
should
be returning "true", because (SHEET1!CD15) is blank. What could
be causing
this problem?

This is my formula: =IF(ISBLANK(Sheet1!CD15),"",Sheet1!BU6)

Thanks, Bill
