Adding data to selected items on a Ref dropdown list

[Justin_Walker]

I am trying to create an invoice worksheet app of sorts.
Within this I am trying to create a drop-down list of employees (which references a sheet) where I can select multiple employees who are working on the job for that day. From that list that I create I would like to be able to input values (rates) to each employee based upon the job they did for that day Then input the hours they worked.

Any help on where I should start looking would be appreciated
