How to exclude old Articles from Recommendation tool

[ben_mrm]

Hello,

I'm working to exclude outdated articles for a recommendation activity but I'm having some trouble with the profile script that is supposed to return the current date minus 60 days, in order to create a 'greater than or equal to' audience to exclude old articles. Here is the script I'm using, seems to be something wrong with the syntax because Target wont let me activate it. Any advise? Is there an easier way perhaps?
