I have 3 entries to be filled out in a worksheet, entry for cell A, comes from a list from another file, I am getting the list with a collection, how do I put the list or the collection on cell A as the only inputs available, after A is selected, with the event worksheet_change I will bring another list of entries from same file to cell B, entries for cell C are similar to B, after is filled row 1, I wan to change the focus to A2, it has to be A,B, and C in that order, How do I pass the collection to the cell A to begin

Thanks
