Help Creating a form

Is there a way for me to upload a list of names for data input?  i.e. a list of employee names for hourly data input.

Is there a way to have a form accumulate data weekly.  For example, paid tips entered each day that will add up over a week by person.

You can use a dropdown field and paste your list of names as dropdown field options. 

If the hourly rate should be entered for all names at the same time, then I would suggest you to use the Input Table field and add names there as rows.

Maybe you can also add the days of the week as columns and edit the submission each day to enter a data for that day and also perform a calculation inside of the table.

You can download your submitted data as an Excel, but you will have to perform your weekly calculation there manually or using some formula.
