Steve,

Just to add to Paul's comment,

I added a line

col = 1

certainly
Dim col as Integer
is useful, but whether you do that or not, the default effect is that col
has a value of zero when you first try to use it and

Cells(1,0) is illegal - there is no Cells(1,0)

so setting col = 1 (or whichever column number you want to start with) as
the first executable command will give it a proper/legal value (for use with
Cells)

I have used the Dim Col as Integer.

Is this what you mean?

I have got this to work with TAB names follwing the help in Excel, however, I
want to read in row headers into a listbox and I can't get it to work.

While worksheets(1).cells(1,col).value < ""
listbox1.additem worksheets(1).cells(1,col).value
col=col+1

Any ideas

Many thanks
