Find a date that is equal to another date plus a specific number of days

I have two columns in a table fsales[Date of Sale] and fsales[Hold Date].

I would like to create a caluclated column that finds where the Hold Date is equal to exactly 14 days after the Date of Sale.

My calculation looks like this but I am not getting any correct data.

End of Trial = IF(fSales[Date of Sale]=(fSales[Hold Date]+14),1,BLANK())

Thanks for your help!
