Invalid Token error

[PowerBINoob24]

Hi all,

I'm trying to create a date table for our fiscal year.  I've been following this article https://www.mssqltips.com/sqlservertip/7133/compute-fiscal-week-calculations-with-power-bi-and-dax/  and it works until I get to step 8.  When I try to create the week ending column using Week Ending = 'Fiscal Year'[Date] - MOD ( 'Fiscal Year'[Date] – 1, 7 ) + 6 I get the following error "The following syntax error occurred during parsing: Invalid token, Line 1, Offset 49, –."

Any ideas?

TIA
