Trying to get measure to work in visual that utilizes column from another table

[jabbajuice08]

Proj_Finish = 

VAR PROJ_FINISH = 
    SWITCH( TRUE(),
        SELECTEDVALUE(Parameters[Risk Type]) = "Low", MAX('Schedule Data'[Finish]) + 90,
        SELECTEDVALUE(Parameters[Risk Type]) = "Medium", MAX('Schedule Data'[Finish]) + 30,
        SELECTEDVALUE(Parameters[Risk Type]) = "High", MAX('Schedule Data'[Finish]) + 0,
        SELECTEDVALUE(Parameters[Risk Type]) = "Very High", MAX('Schedule Data'[Finish]) - 14)

VAR PROJ_ID = 
    CALCULATE(
         MAXX(
             'Accounting calendar'[ID], FILTER('Accounting calendar', PROJ_FINISH >= 
             'Accounting calendar'[MonthStartDate] && PROJ_FINISH <= 'Accounting 
              calendar'[MonthEndDate])) 

RETURN
    CALCULATE(
        SUM(
           'Table'[BLTC GRP]), 'Table'[BL Index]= PROJ_ID, 
           'Table'[IPT]=IF(HASONEVALUE('Schedule Data'[IPT]), VALUES('Schedule Data'[IPT], 
            BLANK()))

So here is my measure I created that dynamically changes the value [BLTC] depending on user selection. Basically, it sums up the BLTC in a new table I created and matches the BL Index to the PROJ_ID I created (This ID is related to the Accounting Calendar). 

My accounting calendar table is attached to my Schedule Data table using two inactive relationships (Schedule Data [FC Index] = Accounting calendar [ID] & Schedule Data [BL Index] = Accounting calendar [ID]). 

My visual is a line graph that already included two other measures to make up the lines. This graph uses Accounting calendar [Date] as the x axis. 

My Proj_Finish measure works perfectly in a table that utilizes fields from my Schedule Data table (Which gives you each tasks' individual BLTC amount). However, it shows up blank when I drag it into my visual because of the Accounting calendar[Date] on the x axis. What am I missing that I need to add on to this measure to make it work for my visual? I need this measure or a new measure to sum up the total BLTC by [Date].

My accounting calendar table is attached to my Schedule Data table using two inactive relationships (Schedule Data [FC Index] = Accounting calendar [ID] & Schedule Data [BL Index] = Accounting calendar [ID]).

That doesn't do you any good. Correct your data model to make a relationship active, either statically or via USERELATIONSHIP

[jabbajuice08]

Sorry, I should have specified. I do use userelationship to activate those relationships. However, my measure I created is dynamic so I can't use userelationship for that to another table.

I thought that's exactly what USERELATIONSHIP is for.  Please provide sanitized sample data that fully covers your issue.
Please show the expected outcome based on the sample data you provided.
