Simple Arrow-change system - Failure

I'm trying to create a very simple system where a 'control center' building allows the use of customization abilities and the unit itself manipulates these.

The building has the abilities 'Coordinate Arrow One' and 'Coordinate Arrow Two', which allow the user to change between four (more to come) shot types via dialog. It saves it in a variable array of up to 24, first 12 for Arrow One, second twelve for Arrow Two. There's also a 12-value array (integer) that determines which of the two shots is currently being used. When the dialog button is clicked, the triggers see if the unit is using shot one or shot two, and depending on the shot and shot being edited, they either simply change the variables or change ability and variable. I have an array for a dialog and a version of the button array for each player. I like arrays :P. This is that trigger:

Here's the dialog trigger:
And here is the trigger that changes current ability when an ability called Arrow Shift on the main unit is used - it's a simple variable change.

Problems:
For some reason, clicking on one ability (I currently have both on one unit for testing purposes) also uses the other. I'm also quite sure that the ability doesn't change. Also, every time I use the dialog ability, it adds on the previous dialog - in essense, it says 'Overall, Range, Cooldown, Speed, Overcall, Range, Cooldown, Speed, and keeps on adding the four every time.

Also, as you may have noticed, the way I organized it requires me to make 24 of the big triggers - two for each player, depending on whether shot one or two is being altered. I didn't want to do it this way, but this editor refuses to let me continue without specifying the index of the array, so if there's any way to compress that into one or two triggers, that would be nice.

In other words, nothing works. Any aid would be greatly appreciated. A lot. And a bit more. I promise.

Set ChangeShotButtonOverall[(Player number of (TRIGGERING PLAYER?!))] = (Last created dialog Button)... Wrong in trigger 2 (the dialog)
I think it should be the owner of triggering unit.

It's the same thing. If the player's unit casts an ability, I can reference that by using 'Triggering Player'. Worked before.

This is a player unit event (convert it in jass and see how the generic unit event works )
So triggering player will work

By the way, triggering player will work as well as owner of triggering player, even if it's an single unit event

Ehh... Is this too long a request to expect assistance in?

Do they have the same OrderId? Are they both based off of the same ability?

Yeah, I noticed and fixed that already. I also changed it so that it cleared the dialog in the dialog trigger before doing anything else, but for some reason it still keeps adding on 4 dialog buttons.
