I have a userform that I would like to auto populate a list box. The value's I want to populate this with are in Sheet3 cells R4:R300. But what I need to do is look at column T and if any value in column T is 12 then the value in column R is what will fill this list box. There could be up to 30 items that would be in this list box. List box is called ListBox 1

Thanks in advance
