Crystal Reports IF Statement/ Formula / Date Qestion

I'm working with Crystal Reports editor and came across the following issue: what I have are 2 date fields & I would like the records to change the colour:

IF DateField1 value is 7 days or less of DateField2 then crRed else crBlack

For example: if DateField1 value is 01/01/2020 and the DateField2 value is 06/01/2020 then the record colour would change to red. If however, we've had something like 01/01/2020 and 01/02/2020 then the record font colour would remain black.

I am unable to work out how to get the extra 7 days off the DateField2. Any help will be highly appreciated!
