Creating a working omnipanel and omnitool system

[ghoststeam217]

If you haven't already noticed I am using the hpl3 engine for this. I am trying to make a map where the player needs to collect an omnitool and cortex chip (or whatever it is that gives the omnitool higher access privileges) and combine them to access a door which can only be opened through an omnipanel.

My problem is I have no idea how to get the panel to work with the omnitool and I can't find anything on the wiki to help me. First of all, the omnipanel doesn't appear to be active and when I equip an omnitool it doesn't allow me to interact with the omnipanel to open the door. Could someone provide a script or small tutorial to describe how to setup an omnitool - omnipanel system to open a door. I know it has something to do with the OmnitoolGui function or something. Thanks.
