Trouble with FileStream loading ints

I am making my first game in monkey, which will be a grid based tower defense game.
i have a 2d array made up of objects with properties Id1 and Id2 which are used elsewhere to determine what to draw in which location.

I am trying to set ids for each object in the 2d array based on a premade file containing ints.

I receive the error "uncaught monkey exception"
Any advice on where i could look to fix this would be appreciated.

Method LoadLevel()
		Local path:String = "monkey://data/level.txt"
		Local File:=FileStream.Open(path,"r")
		
			While File.Eof() = 0
				For Local x:Int=0 Until array.Length() 
		        	For Local y:Int=0 Until array[0].Length()
		        		array[x][y].groundId = FileToRead.ReadInt()
		        	Next
		        Next
		        
				For Local x:Int=0 Until array.Length() 
		        	For Local y:Int=0 Until array[0].Length()
		        		array[x][y].collisionId = FileToRead.ReadInt()
		        	Next
		        Next
			Wend 
			
			File.Close
	End

This is the contents of the file i am trying to load (level1.txt)

The Method ReadInt() reads numbers which were previously written in a not human readable way.
Your text file currently has no such format, so I advise you to use ReadLine() or ReadString() instead.
You can than split the string apart into pieces by using Split()

e.g.

Local str:String = FileToRead.ReadString() 'Or ReadLine which will only read a single line (might be easier to handle for you)
Local myNumbers:String[] = str.Split(" ") ' Start a new entry when the space character shows up

.... To convert a string to Int you can use

Int(myNumbers[index])

Then maybe something like....

to access the right number use 

myNumbers[height*y + x]
