condition in button "select field"

[rafael5958]

In qlikview, I have to put a contidion in a "search character" of a select field in a button.

I must select fields with 10,20,80.

The only way it work was putting

=num(10)      so it select only 10

If I put

=num(10) or num(20) or num(80)  

or

=num(10) | num(20) | num(80) 

It doesnt work and I cant select all fields. Is there a way to solve it ?
