I have three userforms, each with a combobox that I need to populate with
items from the same worksheet. Also each list that populates each combobox
has the possibility to increase is number of items. The name of the
worksheet the holds all the data is "Items"

1) This is the largest and can probably use a feature I have seen where the
command scrolls up to the last empty row. I need to pull item number and
item description from "Items". Starting cell for each is A3 and B3
respectfully. Ending cell is unknown due to the possibility of adding new
items. However, I will not enter any data having to do with anything else
past the end of the list. I only need to populate with the item number but
need to be able to place the item number and corresponding item description
in the appropriate cells (already have code to place data in cell).

2) Currently, I have station numbers 1-7 in C3-C9. This may be added to if
a new EMS station is built, ie station 8 would be in C10. How do you
populate a combobox using same row. NOTE: I have data to the right of this
list that pertains to another combobox (see #3).

3) Currently I have a list of the ambulance numbers (M1, M2, M4, M7, etc) in
a list starting with M3 and listing down the sheet. I am not sure if you can
pinpoint that column and still do a command that locates the last empty cell
in that column or not. For this example, let's say M3-M20 contains each unit
number, with the possibility of adding more.

Thanks!
