Identify correct country from measure when two countries are returned in result

[Pandadev]

I have a measure that detects the country based on max hours spent there.

But there are some instances where the result has more than one country as the hours spent are matched. so as an example

it could be United States , Canada. this is returned in a measure called max_country

I also have a column called op_country

What I am trying to create is a dax formula first looking to see if the max_country measure result contains a comma

If it does then if country before the comma equals op_country then keep that country

if country after comma equals that country then keep that country

else keep both countries

@Pandadev Sorry, having trouble following, can you post sample data as text and expected output?

Country_Max_Days	Op_Country
Netherlands	Netherlands
Spain , France	Netherlands
Netherlands	Netherlands
Germany , Netherlands	Netherlands
Netherlands , Germany	Netherlands
Netherlands	Netherlands
Netherlands , Germany	Netherlands
Netherlands	Netherlands
Netherlands	Netherlands
Netherlands	Netherlands
Netherlands , Germany	Netherlands
Netherlands	Netherlands
Netherlands	Netherlands
Netherlands , Germany	Netherlands

So if Country_Max_Days contains a comma , example Netherlands , Germany , then I would need a dax formula to look at first country before comma , Netherlands and if that matches the Op_Country value then return that country.  If not then check the second country and see if that matches. The desired output would be

Country Max Days	Op_Country	Output
Netherlands	Netherlands	Netherlands
Spain , France	Netherlands	Spain , France
Netherlands	Netherlands	Netherlands
Germany , Netherlands	Netherlands	Netherlands
Netherlands , Germany	Netherlands	Netherlands
Netherlands	Netherlands	Netherlands
Netherlands , Germany	Netherlands	Netherlands
Netherlands	Netherlands	Netherlands
Netherlands	Netherlands	Netherlands
Netherlands	Netherlands	Netherlands
Netherlands , Germany	Netherlands	Netherlands
Netherlands	Netherlands	Netherlands
Netherlands	Netherlands	Netherlands
Netherlands , Germany	Netherlands	Netherlands

@Pandadev  is Country_Max_Days a column /measure?

If it is a measure, you can write a measure like this

_output =
SWITCH (
    TRUE (),
    CONTAINSSTRING ( [Country_Max_Days], MAX ( src[Op_Country] ) ), MAX ( src[Op_Country] ),
    [Country_Max_Days]
)

Thanks , but I needed to know if it was the first country or 2nd country , as I also need to know which city to select , as I also have a measure that provides the city name.

So if the country combo was Netherlands , Germany , I would also need to get the correct city , so that measure would show , Amsterdam , Cologne. So as the first country was the match , I would want the first city
