Select column of a datagrid

[Wouter]

Hi,

How do I select a column of a datagrid and put his number or caotion in a variable.
e.g.
When I select column 3 I want to find a way to get that 3, so that I can give a variable the value 3.

Regards

Nevermind
I already found the solution, the headclick function.
