Slicer Visual multiselection error

Hello miTutorials 

I solved the issue it was falut on messure i modified messure with in function now its is display 3 month data too i mean multi select is working 

could you assit me on another query ? 

let me share my sceanario on this dashboard as you can see 2 slicer 1 matrix and 123 card 

now i am using this custom table for filter data so on 2 slic i add property column and Custom date column

here is custom table which is take 3 information from all table 

now on matrix  column area i use leasing agent from custom table to see as header 

and on 2 slic i add property and custom date from custom table 

problem is on card 123 i use measure to see total or value 

so on card i use this measure 

Lead conversion First visit to 1 =

ROUND(CALCULATE(

    DIVIDE(

        SUM('Conversion'[Applications Completed]),

        SUM('Conversion'[First visit/tour])

    ) * 100,

    ALLEXCEPT('CustomTable', 'CustomTable'[Property], 'CustomTable'[CustomDate])

),1

)

but it doesnt work mean showing me wrong value 

but if i remove property and custom date from custom table and use own table column it is showing perfect value
