Does your ComboBox have 80 columns? If the ComboBox1.ListIndex = 1 Then the
statement ComboBox1.List(ComboBox1.ListIndex, 80) would be trying to return
the combo box value for row 1, column 80 of the combo box list, not the
worksheet.

Greetings,

I am trying to set a CheckBox to either true or false depending on if
the value on row 1 column 81 is "X" or empty

I have this statement in a sub:

__________________________________________________ _________
....
If ComboBox1.List(ComboBox1.ListIndex, 80) = vbNullString Then
.....
__________________________________________________ _________

That keeps coming up with an invalid argument error. I don't
understand, the elements of the argument appears to be correct.

It's supposed to see if the value on row 1 in the 81st column of the
ComboBox List is empty or not (a checkbox loaded it with an "X" or ""
when the record was created)

Debug shows the value of the ListIndex as 1 which is correct.

Can anyone advise as to where or what could be causing this problem?

Any help will be appreciated.

Thanks for looking at my question.
