TD: How to toggle display ONLY on a single unit

Hello everyone!

I'll cut to the chase: I've read for a while and searched but I couldn't find a real solution to an issue I'm encountering here.

I'm making a TD, and I'm starting with the deployment system. I'm making it with an isometric view, already sorted out many things. But I'm having a problem with the display of the units. I want to select a unit, and it should display the range, and upgrade button and a sell button. I made a container, and a local variable to set if it's selected or not, and depending on that if it displays it. But the thing is that I want only one to be selected, if I select another one it should turn the others off. Here's a graphic example, the events and the capx.

Thanks!

Deploy and Display Info

Update: I have found a solution, I don't know if it will bring future problems, but as for now is actually better since I'm not spawning new objects and have to hide them. It has less events I think.

I'm sure it simple, but yet I can't find a way to call the funcion OnScreenReset when I touch the background. If I add an event that triggers when it touches the BG, then nothing works.

Any ideas?

Here's the updated capx

Deploy and Display 2

Edit: I've found the way to do it, just a simple fix. Here it is:

That leaves everything (as for today <img src="smileys/smiley2.gif" border="0" align="middle"> ) fixed.

Maybe this will help someone.
