GetChar related?

I have my tilemap editor loading and saving maps perfectly.

The thing is it's only perfect if I pick the correct file.

Take a look at this code. This is part of the mapfile loading.

Function SelectMap() 
		If TFile.DoneLoadingMaps = 1
			Local Line$
			Local MapIdSelected:Int = 0
			Local LoadTheMap:Int = 0
			
			Local f2:TStream
			Local File:String
			Local f:String
			
			Repeat
				Cls
				For Local f:TFile = EachIn TFile.FList
					f.DrawMapName
				Next
				
				If KeyHit(KEY_ESCAPE) 
					TFile.DoLoadMap = 0
					For Local f:TFile = EachIn TFile.FList
						f.id = 0
					Next
					TFile.FList = Null
					TFile.TempID = 0
					TFile.TempY = 100
					TFile.DoneLoadingMaps = 0
					Exit
				End If
				
				Local OutputText:String = " Enter Map Number to Load : " + Line$
				DrawText OutputText, 280, 500
				If MilliSecs() mod 800 < 400 Then DrawRect(280 + TextWidth(OutputText), 500, 2, TextHeight("|")) 
				Flip
				Local char:Int = GetChar() 
				If char<>0 Then
					'Print char 'Debug porpouses, check for spetial characters not being displayed in the BM window becouse of a incomplet default font.
					Select True
						Case char >= 32
							Line$ :+ Chr(char)
							
						Case char = 8 ' backspace
							Line$ = Line$[..Line$.length - 1]
							
						Case (char = 27) ' or (char = 13)  ' escape and enter
							Line$ = Null
							
						Case (char = 13)  
							MapIdselected = 1
							Exit
					End Select
				EndIf
			Forever
									
			If MapIdSelected = 1
				'TTile2.MapClearMap
				Print "2"
				For Local f:TFile = EachIn TFile.FList
					Print "3"
					If Line$ = f.id
						Print "4"
						File = f.MapName
						f2 = ReadFile("usermaps/" + File) 
						 	
							For Local y:Int = 0 Until FMHeight
								For Local x:Int = 0 Until FMWIDTH
									FactoryMap[x, y].id = Readint(f2) 
								Next
							Next
						Print "Yay - Loaded"
					Else
						End
					EndIf
				Next

				If MapIdSelected = 1
					CloseFile(f2) 
					MapIdSelected = 0
					TFile.DoLoadMap = 0
					For Local f:TFile = EachIn TFile.FList
						f.id = 0
					Next
					TFile.FList = Null
					TFile.TempID = 0
					TFile.TempY = 100
					TFile.DoneLoadingMaps = 0
				EndIf
			End If
		EndIf
	End Function
	
End Type

I store the maps in a type and assign an ID "number from 0 and above".

The offending bit of code is here.

			If MapIdSelected = 1
				'TTile2.MapClearMap
				Print "2"
				For Local f:TFile = EachIn TFile.FList
					Print "3"
					If Line$ = f.id
						Print "4"
						File = f.MapName
						f2 = ReadFile("usermaps/" + File) 
						 	
							For Local y:Int = 0 Until FMHeight
								For Local x:Int = 0 Until FMWIDTH
									FactoryMap[x, y].id = Readint(f2) 
								Next
							Next
						Print "Yay - Loaded"
					Else
						End
					EndIf
				Next

Basically I store what GetChar gets in Line$.

I then use an eachin loop to detect if line = f.id.

If it equals f.id it loads the correct map according to what number was input. When I add an...

else
end


it quits even if the correct f.id was picked.

Why is it doing this?
