Artificial selection in List Box

[lylererger]

Hi Guys!

How to make some wonder selection like if I'm selecting one value in list box then selected 2 or 3 values?

Something like on screenshot below

and so on...

I need some function like "SelectFields"

Is that possible at all?

Thnx.

Add a Select in Field action to the OnSelect field trigger of the No field on the Triggers tab of the Document Properties window. Use No as field name and as search string ='<=' & max(No)

Gysbert, I too understood that via triggers it is necessary to do. But about construction ='<=' Max(No) didn't guess. Thanks a lot.
