Posts: 15                Listbox2.DeleteAllRows

Dim num As Integer
Dim sum As Integer

num = Val(Listbox1.Cell(-1,1))
sum = num * 6

Listbox2.Cell(-1,1) = str(sum)


Could anyone give me a clue as to why Listbox2 is not displaying any data? I 
have this under the Sub Action() for a PushButton if that makes any difference.

That seems strange, as it should return a delimited string of all the values in 
column 1.  You then set the values of column 1 in all the rows of listbox2, but 
there are no rows, so it does nothing.
Quote:num = Val(Listbox1.Cell(-1,1))
This is essentially

num = Val(ListBox1.Cell(0,1))
Quote:Listbox2.Cell(-1,1) = str(sum)
Change this to

Listbox2.Addrow str(sum)

Posts: 15                -1 is how you tell it to select all rows is it not? I 
need it to select the data in the 2nd column of all the rows. I'm thinking I 
can do it 1 row at a time and just add a loop to it to increase the row by 1 
until it gets to the end. Would that work?

a delimited string.  You'd still have to parse it out and loop through the 
values.  Best to loop through each row of the listbox and handle each one 
separately.
