Show a substring in Data Grid 2

Hey,  is it possible to show a substring of an attribute in Data Grid 2? Because when I try to show the column as Dynamic Text like substring($currentObject/Attribute,5) then the column is always empty. Edit: I realized that the problem is not the substring but the Dynamic Text. For some reason I always get empty results. It works fine, when I change the column setting back to attribute. Does anyone know, what the problem could be?   Grateful for any help.

Yep, that works. Mind you, substring($currentObject/Attribute,5) will show all characters, starting with the sixth character (yep, not the fifth). So the result will be empty if your attribute only contains 5 or less characters.

Figuring out what happens is easier if you add a column next it showing the full content of currentObject/Attribute.
