Error When Referencing Field Parameter in a Measure

[smithmpi]

I have a measure that dynamically returns a chart title based on slicer selection.

Now I want to add to the measure a field parameter that will determine the chart title based on the slicer selections AND the field parameter selection. However, I get an error when trying to do so. 

Is it even possible to implement what I'm trying to achieve? Appreciate any tips please @bhanu_gautam @lbendlin 🙂

Note: the field parameter is referencing measures only and for each of the measures referenced, they too are referencing other measures. Hope that makes sense.

Dynamic Chart Title = 
VAR FieldParameter = SELECTEDVALUE('Ethnicity Filter'[Ethnicity Filter])
VAR Slicer1 = SELECTEDVALUE('Gender and Ethnic Pay'[Business Unit 1])
VAR Slicer2 = SELECTEDVALUE('Gender and Ethnic Pay'[Business Unit 2])
VAR ChartTitle = 
    IF(
        ISBLANK(FieldParameter),
        "ALL ETHNICITIES",
        FieldParameter & " REPRESENTATION"
    )
RETURN
SWITCH(
    TRUE(),
    ISBLANK(Slicer1) && ISBLANK(Slicer2), "MPI - " & ChartTitle & " by TENURE",
    NOT ISBLANK(Slicer1) && ISBLANK(Slicer2), UPPER(Slicer1) & " - " & ChartTitle & " by TENURE",
    NOT ISBLANK(Slicer1) && NOT ISBLANK(Slicer2), UPPER(Slicer2) & " - " & ChartTitle & " by TENURE"
)

//Field Parameter
Ethnicity Filter = {
    ("European", NAMEOF('Measures - General'[European Rate]), 0),
    ("Other Ethnicity", NAMEOF('Measures - General'[Other Rate]), 1),
    ("Asian", NAMEOF('Measures - General'[Asian Rate]), 2),
    ("Māori", NAMEOF('Measures - General'[Māori Rate]), 3),
    ("Pacific Peoples", NAMEOF('Measures - General'[Pacific Rate]), 4),
    ("MELAA", NAMEOF('Measures - General'[MELAA Rate]), 5)
}

During troubleshooting you will want to keep it simple.  Recommendation is to expand all measures and avoid nesting.

Hi @smithmpi,

Could you please share a pbix or some sample data that maintains the original data structure and expected results? This will help us clarify your situation and test the coding formulas.
Best regards,
