Dynamic filter formula

[Ash2]

Hi All, 

i wanted to know if there is a way to set a variable and then user it as a formula in a filter function?

Set(Vartest,Left(Concat(Country,"'Country Text Lookup' = "&""""&Title&""""& " Or "),Len(Concat(Country,Title & " Or "))-9))

then use the above in a filter 

Filter( SharepointList, Vartest)

something like the above.

You would need a column in the list to compare it to, but you can use variables.

Filter( List, Vartest = ColumnName) 

You could use 'in" or another test. You could also use multiple tests in your filter instead of that complex variable.

It all depends on what data you are trying to find.

I made a little mistake there explaining what im trying to do. 

Set(Vartest,Left(Concat(Country,"'Country Text Lookup' = "&""""&ColumnName&""""& " Or "),Len(Concat(Country,Title & " Or "))-9)) = this formula collected all the country a user has access too, this is done when the user firsts log in. 

so if user is in 3 country the Vartest will have a value like this 'Country Text Lookup' = "UK" Or 'Country Text Lookup' = "USA" Or 'Country Text Lookup' = "Canada"

"Country Text Lookup" is a Column that exists within a  SharePoint List called ListABC 

so if i user Vartest in a filter function would it give me something like the below ?

Filter( ListABC , 'Country Text Lookup' = "UK" Or 'Country Text Lookup' = "USA" Or 'Country Text Lookup' = "Canada")

That Filter will only return the rows that 1 of those countries listed. I'm still not exactly sure what you are trying to accomplish. Are you trying to limit access to certain parts of the app depending on the country listed? Are the countries listed in the Country field, but you have multiple ones in the field?

How many countries are you dealing with? There may be better ways to accomplish this.

exactly as you said,  im trying to limit the access to certain items within a gallery/app with this.

so there is two lists 

1) with country's and users who have access to that country 

2)  work orders and the country its in

in total there is about 100 country
