Assigning action variable through Description processing isntructions

(imported topic written by NivS)

In some SCM fixlets, the operator can manipulate values through the use of HTML buttons and boxes.

I’m trying to mimic that ability but can’t figure out how to read the selection the operator makes in the Description panel.

The sample code I’m using in the Edit Processing Instructions dialog to create the box is:

(html "<select name=%22something%22><option>Option1</option><option>Option2</option><option>Option3</option><option>Option4</option></select>")
