relationship

Dear community,

I had two unconnected tables the source table is an appended one the second is a reference from the first because I unpivoted some columns.
as I have read to connect them there are functions such as (related or treatas) but I didn't success using them. also, I don't know if this is the right solution.
now I have two tables with common columns I need to have them as one
so what I need to do is to have the category column (Times of displacement)which contains (First, Second, Third and More) as a slicer and the value column (Value_Times of displacement) in cards

i hope that was clear,

let me know if you need further clarification

thanks in advance,

Nour
