What is wrong with my filter() formula?

[Anonymous]

Total Attended Appointment = CALCULATE(COUNT(UCS_Appointment_Data[a_appointid]),FILTER(Conversion_Code,[PowerBI_Appt_Code]="Intake Assessment") && FILTER(POWERBI_ATTENDANCE,POWERBI_ATTENDANCE[POWERBI_ATTENDACE]= "Attended"))

This is my relationship table.

 I can only use it for 1 filter() but not two :C

pls try this

Total Attended Appointment = 
CALCULATE (
    COUNT ( UCS_Appointment_Data[a_appointid] ),
    ( [PowerBI_Appt_Code], POWERBI_ATTENDANCE[POWERBI_ATTENDACE] )
        IN { ( "Intake Assessment", "Attended" ) }
)

Error is still showing: 

Do you need other details?

you can see what kind of error before the name [PowerBI_Appt_Code] you need to specify the name of the table

Total Attended Appointment = 
CALCULATE (
    COUNT ( UCS_Appointment_Data[a_appointid] ),
    ( 'Conversion_Code'[PowerBI_Appt_Code], POWERBI_ATTENDANCE[POWERBI_ATTENDACE] )
        IN { ( "Intake Assessment", "Attended" ) }
)
