You'll use a formula in the selection criteria instead of one of the options from the Select Expert but you have to go to the Select Expert to start. If you don't have anything set up in here already, select a field - doesn't matter what it is.
Click on the Formula button and add something like the following to the the formula:
{table.DateField} >= (CurrentDate - 3) and {table.DateField) < CurrentDate
NOTE: This assumes you don't want the current date. If you do, change the "<" to "<=".
