Using DAX to create custom URL

Hello! I'm using  DAX measures to create custom URLs based on the visual the end-user is seeing.  I'm using a value from a static table as part of the measure - ('YEAR'[YEAR]), see below. 

The problem I'm having is that sometimes the custom URL works. sometimes it doesn't.  Example:

• "http://www.oabis.state.pa.us/SGWS/"& SELECTEDVALUE('YEAR'[YEAR]) &"/"& SELECTEDVALUE('YEAR'[YEAR]) &"_SGWS_Dashboard_Charts.pdf#page=4" works, where  ('YEAR'[YEAR]) = 2021

but

• "http://www.oabis.state.pa.us/SGWS/"& SELECTEDVALUE('YEAR'[YEAR]) &"/"& SELECTEDVALUE('YEAR'[YEAR]) &"_SGWS_Dashboard_Charts.pdf#page=5" doesn't work.

I'm at wit's end trying to figure this out.  I can hard code SELECTEDVALUE('YEAR'[YEAR]) to 2021, but that means next year when this report comes out, I have to do the same things to the other URLs.

Am wondering if anyone else came across this issue and has a solution.  Thanks!
