Dax Measure for Commission Amount based on # Sales Between Two Numbers

[lbrown]

I am attempting to create a dax measure that will calculate the total commission amount based on a filter of "eligible for payout" and the # Sales between two numbers. So if Validation 1 Column = "Eligible for Payout" and the # Sales Column is between 0-6 then I want to take the # Sales * the $ amount per sale.

Example: If Validation 1 Column = "Eligible for Payout" and the # Sales Column = 16 then I want to take 16 * $14 to get $224.

Another Example: If Validation 1 Column = "Eligible for Payout" and the # Sales Column = 5 then I want to take 5 * $7 to get $35. 

Want I want to see in a Power BI Table is this: 

Validation 1	# Sales	Commission Amount
Eligible for Payout	16	$224
Eligible for Payout	15	$210
Eligible for Payout	15	$210
Eligible for Payout	9	$81

What I currently have in a Power BI Table is this:

 

The Commission Tier is this:

So, probably something like:

Measure =
VAR __sales = MAX([# Sales])
VAR __commission =
  SWITCH(TRUE(),
    __sales<=6,LOOKUPVALUE('Commissions'[$/Sale],'Commissions'[#Sales],"0-6"),
    __sales<=9,LOOKUPVALUE('Commissions'[$/Sale],'Commissions'[#Sales],"7-9"),
    __sales<=14,LOOKUPVALUE('Commissions'[$/Sale],'Commissions'[#Sales],"10-14"),
    __sales<=19,LOOKUPVALUE('Commissions'[$/Sale],'Commissions'[#Sales],"15-19"),
    LOOKUPVALUE('Commissions'[$/Sale],'Commissions'[#Sales],"20+")
)
VAR __eligible = MAX([Validation 1])
RETURN
IF([Validation 1]<>"Eligible for Payout",0,__sales * __commission)

Thanks Greg,

I am receiving an error message on the If statement for [Validation 1] column. I forgot to mention the commission values are in a separate table titled "FL Commission Rates" and the query table holding the data is in a table titled "FL Agents Commission". There's no unique identifier to create a relationship between these two tables. Any suggestions on how to fix the error message?

Also, should the [# Sales] column be the column from the "FL Agents Commission" table which is actually a measure to get the count of comissions per agent or should I use the [# Sales] column from the "FL Commission Rates" which is the chronological number from 0-20 in a column? I'm a little confused on this part.
