Time stamp to event UUID

Hi, I have the following two example tables in my data:
 
EVENTS

I need to add a calculated column to the events table with the following conditions
 
EVENTS[Node] = CHECKS[Node]
EVENTS[TimeStamp] <= CHECKS[ENDDATE]
EVENTS[TimeStamp] > PREVIOUS CHECKS[ENDDATE]
 
The end result would look like this:
 
EVENTS

I tried to look for a solution but couldn't find one. How can I use DAX to build this calculated column?
Thanks!

@ChipTz try this and check if it works for you

Column = CALCULATE(MIN(Check[UUID]),FILTER(Check,Check[ENDDATE]>=Event[TimeStamp] && Check[Node]=Event[Node]))

Thanks for the fast feedback. It did work on the example data I posted but it is not working on my real data. I need to check what is wrong wiht my data 😐

 

I don't get why MIN is the function that solves this, tough. I was expecting something as SELECTEDVALUE.
