Pass measure value to a dax function variable

[Anonymous]

I have a what - if-parameter :

Vals = GENERATESERIES(1, COUNTA(Sale[Row ID]), 1)

Count = SELECTEDVALUE('Table 1'[Vals])

Now the data in count needs to be passed to var size of below dax function .. how is that possible

Rand Function Table =

VAR Size = 12

VAR TableWithRand =

    ADDCOLUMNS ( Sales, "Rand", RAND () )

RETURN

    TOPN (Size, TableWithRand, [Rand] )

Hi @Anonymous 

if I understand you correct didnt you try simple

Rand Function Table =
VAR Size = SELECTEDVALUE('Table 1'[Vals])
VAR TableWithRand =
    ADDCOLUMNS ( Sales, "Rand", RAND () )
RETURN
    TOPN (Size, TableWithRand, [Rand] )

?
