Calculate a measure based on selectedvalue or other measure

[elaj]

I have a problem with a measure.
I need to change "cat_1" over another slicer.

Measure_1 = CALCULATE([Total], table[Category] == "cat_1")

This works... but is not flexible for my needs.
I know i could filter the whole visual over "cat_X"... and just use the [Total] measure, but it is not possible, because my axis shouldnt be filtered by that.
I tried to do this:

Measure_1 = CALCULATE([Total], table[Category] == SELECTEDVALUE(table[Category]))

Not possible... i dont know why... because SELECTEDVALUE(table[Category]) should return the string "cat_X"... and it does... inside of a card visual.
Even:

filter = "cat_1"
Measure_1 = CALCULATE([Total], table[Category] == filter)

is not working. I dont know why.
Do you know a solution?

Its weird... 

Measure_1 = 
VAR sel_value = SELECTEDVALUE(table[Category])
VAR result = CALCULATE([Total], table[Category] == sel_value )
RETURN
result

but this is working.
