[ryan oconnor]

Ok i will try to explain this exactly. i have a table which i have both data validation and v look up being used in it. The employees will pick a description of the item off the lists in the A column and when they are at the bottom of the table i need the table to add a new row at the bottom of the table that has the data validation and vlookup in the row automatically so they can continue to expand the list until they have all the items listed that they need for that job. i need to know how to set this table up to expand automatically if that is at all possible or the best way to accomplish the task. below is the file i am creating that needs help.
