Help Please.

I am trying to use:

SUM(
SELECT(
Inventory[Amount],
([Item ID] = [_THISROW].[ID])
)
)

To Run an accumulative amount, But I want to compare the Item ID and Item Color

Item ID: 01, 02
Item Color: Red, Blue

All Counts 0

Input 3 for 01, Blue
Input 2 for 01, Red
Input 5 for 02, Blue 
Input 1 for 02, Red

Current Counts:
01, Blue = 3
01, Red = 2
02, Blue = 5
02, Red = 1

Is there a better way, I am lost.  Thanks for any help in advance

It seems like if you create an Inventory table with this definition

id: UNIQUEID(), itemId, color, amount.

Then this seems exactly what you want without any expressions.

I have that table already, but I am using another table to update the amounts!
