how to do switch doors and other switch related things

hey yall scott here, another simple question from a first timer map maker. so im using UDB (ultimate

doom builder) and im wondering how to make a switch open a door in udb im looking at a guide on doom wiki but im just not getting it, its just not working

Let's say we have an architecture such as this, a door and a switch with which we open said door.

To construct the door we employ the built-in "Make Door" routine (Shift+D from Sectors Mode) from

where you can choose the textures for the door and let it assign a tag.

Then at the switch assign an action special to open the door and also assign the same tag as given to the door sector.

Also remember to check the "Repetative action" field if you want to use the switch multiple times.
