How to return values from table2's column if two columns from table2 are equal to table1's columns

Hello, 

My task is to create a custom column labeled "Assigned Hours" in the Cases query that returns Blocks[Assigned Block Hours] when Cases[SURGERY_DATE] = Blocks[SURGERY_DATE] and Cases[Room] = Blocks[Room]

At first, I tried:

if [SURGERY_DATE] = Blocks[SURGERY_DATE] and [Room] = Blocks[Room] then Blocks[Assigned Block Hours] else null 

Then, I tried Table.ContainsAll and List.PositionOf but I've been having issues since I'm trying to look up two values rather than one.

Here is my desired outcome:

*This is just an example, not my actual data. Tables have different number of rows and columns. Any help would be greatly appreciated. Thank you.

Here are a few columns from Table 1 titled Cases

Here are a few columns from Table 2 titled Blocks
