I am using excel 2007. I am using the vlookup to help auto fill information into the work sheet. The problem I am having is that one for the cells I am auto filling has to be a drop down list so I can select between two options for the specific auto fill information. For example, I auto fill information about a person, which would include first and last name and other pertinent information. On one of the auto fill cells, I need to be able to select between two different numbers that is unique to that individual. I need to select on of two numbers that the individual is using for that day. The problem is that I do not know how to incorporate a drop down list as part of my vlookup formula. Basically I need to be able to auto fill all my information (which I have working fine) but also need to auto fill the cell that will allow me to choose between the specific numbers unique to that individual. any help would be great, thank you.
