Touched event not working when updating a region3?

Hi guys. im kinda new here. Been looking for a roblox help fourm for a while now and found this site. weird verification thingy .... o.0!

Anyway My Problem: i've written a script that clones a part or a model depending on how a user configures it.

The script checks for 2 things,the checks are as follows:

1) check if the script can find the model to be cloned

2) (Optional) Check to see if the user wants to use a button to clone the model with ie: click a ClickDetector/ touch a Part or using one of the Gui Element buttons to clone the model.

If the user hasn't got a button, the script will use a 5 sec timer to check for the spawn point of the model to be cloned to see if its clear. If its not then just sleep.

The problem im having is when you touch a part in the workspace it keeps saying the spawn point is not clear when in reality i've removed the model from the workspace!

For the life of me im unsure what is going on but when you dont specify a button the script works as intended! But with a button it seems to think the model is still at the spawn point... o.0!

i know in the past this would work but am i calling the Touch event wrong or do i need to envoke the server from local script inside the button or player? im confused lol

The code i wrote (in full!) is below

Code:

--// name of your model or part you want to clone
local Model_Or_Part_Name = "Observation Tower"
--// change this to the button your using (optional!)
local Button_Name = "Part"

local CloneMETime = 5 --// in seconds!
local CloneDisableTime = 5 --// time to disable the button in seconds, this is to stop spamming of the button (if set!)
--// this is for your button if its touchable ingame!
local TouchedColor = Color3.fromRGB(0,0,0)

Any help would be appreciated!
