[Trigger] Failed "detect nearest unit" trigger, need halp

[TwistedFirestarter]

So this is what its supposed to do:
The targeted hero is tied up to the nearest object within 250 range, whether its a tree, a unit, or a building.
If there are no units, trees, or buildings the targeted hero will be ensnared.

Currently the effects are all over the place. From my tests, the code in the destructible and "no units, tree or building" part is sound a.k.a the beginning and end are fine. Just the massive bulk in the middle is riddled with bugs that i cannot seem to see.

I think the bug(s) have/has got to do with detecting whether or not the system has picked up a "nearest unit" and how it stores this info. Anyway, please and thank you.

Here's the bit about picking the nearest destructible/unit:

• Tie Emp Up
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Tie Em Up
  • Actions

    • Floating Text - Create floating text that reads moi at Temp_Loc_2 with Z offset 0.00, using font size 10.00, color (100.00%, 100.00%, 100.00%), and 0.00% transparency

The floating text is there so you can see that it works.

Perhaps you can work on from there.
