Let measure show the correct total amount in a table

[An0n]

I have implemented the below based on a solution provided on this forum to show amounts from different tables as columns based on the union of IDs. However, the totals show zero for all columns based on the picture in step 3. How can I fix this?

1. Create a dimension table with IDs which is from both Table 1 and Table 2

IDs = DISTINCT ( UNION ( VALUES ( 'Table 1'[ID] ), VALUES ( 'Table 2'[ID] ) ) )

2. Create the measures as below to get the sum of amount in Table 1 and Table 2, the difference of amount

Amount_t1 = 
VAR _selid =
    SELECTEDVALUE ( 'IDs'[ID] )
RETURN
    CALCULATE (
        SUM ( 'Table 1'[AMOUNT Table 1] ),
        FILTER ( 'Table 1', 'Table 1'[ID] = _selid )
    ) + 0

Amount_t2 = 
VAR _selid =
    SELECTEDVALUE ( 'IDs'[ID] )
RETURN
    CALCULATE (
        SUM ( 'Table 2'[AMOUNT Table 2] ),
        FILTER ( 'Table 2', 'Table 2'[ID] = _selid )
    ) + 0

Difference of Amount = [Amount_t1]-[Amount_t2]

3. Create a table visual as below screenshot

hi @An0n 

try like:

Amount_t1 =
VAR _selid =
    SELECTEDVALUE ( 'IDs'[ID] )
VAR _value1= 
    CALCULATE (
        SUM ( 'Table 1'[AMOUNT Table 1] ),
        FILTER ( 'Table 1', 'Table 1'[ID] = _selid )
    ) + 0
VAR _value2= 
    CALCULATE (
        SUM ( 'Table 1'[AMOUNT Table 1] ),
        ALL('Table 1'[ID])
    ) + 0
RETURN
IF(_selid <> BLANK(), _value1, _value2 )

if it works, similar part could added to Amount_t2.

Hi @An0n 
Please use

Amount_t1 =
SUMX (
    VALUES ( 'IDs'[ID] ),
    VAR _selid = 'IDs'[ID]
    RETURN
        CALCULATE (
            SUM ( 'Table 1'[AMOUNT Table 1] ),
            FILTER ( 'Table 1', 'Table 1'[ID] = _selid )
        ) + 0
)

Amount_t2 =
SUMX (
    VALUES ( 'IDs'[ID] ),
    VAR _selid = 'IDs'[ID]
    RETURN
        CALCULATE (
            SUM ( 'Table 2'[AMOUNT Table 2] ),
            FILTER ( 'Table 2', 'Table 2'[ID] = _selid )
        ) + 0
)
