Lookup value based on value falling within range on other table

[SandyBL]

Looking to create the "Actual Rate" column in a table based on a rate card table that has the rules on which rate to use for each volume level.  So need help with the Actual Rate column.  I can do this in Excel but not getting it in PowerBI

Table 1: Rare Card

Rate    Min Volume      Max Volume

$5       0                        10,000

$4       10,001                11,000

Table 2: Volume Delivered

Actual Volume     Actual Rate

10,500                  $4

Hello, try this in a calculated column in Table2 (Volume)

ActualRate =
CALCULATE (
    VALUES ( Rates[Rate] ),
    FILTER (
        Rates,
        Rates[Min Volume] <= Volume[Actual Volume]
            && Rates[Max Volume] >= Volume[Actual Volume]
    )
)

If I need to write the same query logic in while add custom column in Edit Queries Then how we can write ?

Just realized its more complex than that

Table 1: Rare Card

Rate    Account        Min Volume      Max Volume

$5        1                          0                        10,000

$4        1                         10,001                11,000

$8        2                          0                        10,000

$7        2                         10,001                11,000

Table 2: Volume Delivered

Account    Actual Volume     Actual Rate

1                   10,500                  $4

So the rate card table has the same min and max volumes repeated for different accounts, so when using that formula it has mutliple Rates that fall within the same range and I get an error.  How do I filter to look at the specific account first before looking at the range?

ActualRate =
CALCULATE (
    VALUES ( Rates[Rate] ),
    FILTER (
        Rates,
        Rates[Min Volume] <= Volume[Actual Volume]
            && Rates[Max Volume] >= Volume[Actual Volume]
           && Rates[Account]= Volume[Account]
    )
)
