I am having trouble with this again

OK. I know we have went over this and I have had this figured out but I accidently deleted the working one and... yeah. So here is my troubled code.

Graphics 400,200,32,2

Global t,msg$,serv,the_name$,the_stream,msg1$,msg2$

Type user
	Field name$
	Field stream
End Type

Global u.user

serv=CreateTCPServer(49494)
If serv=0
	End
EndIf

While Not KeyHit(1)
t=AcceptTCPStream(serv)

If t<>0
	msg$=ReadLine(t)

	If msg$="[LOGIN]"
		msg$=ReadLine(t)
				
		u.user=New user
		u\name$=msg$
		u\stream=t
				
		SendServerMessage(Upper$(msg$)+" HAS LOGGED ON")
	EndIf
EndIf

For u.user=Each user
	If Not Eof(u\stream)
		If ReadAvail(u\stream)>1
			msg$=ReadLine(u\stream)
			If msg$="[MSG]"
				msg1$=ReadLine(u\stream)
				msg2$=ReadLine(u\stream)
						
				SendUserMessage(msg1$,msg2$)
			ElseIf msg$="[LOGOFF]"
				msg$=ReadLine(u\stream)
				the_stream = u\stream
						
				DeleteUser(the_stream)
					
				SendServerMessage(Upper$(msg$)+" HAS LOGGED OFF")
			EndIf
		EndIf
	Else
		the_name$=u\name$
		the_stream=u\stream
			
		DeleteUser(the_stream)
			
		SendServerMessage(Upper$(msg$)+" HAS LOGGED OFF")
	EndIf
Next ;MAV ERROR HERE;

Delay 1

Wend
CloseTCPServer serv
End

Function SendServerMessage(txt$)
	For u.user=Each user
		If u\stream
			WriteLine u\stream,"[SERVER]"
			WriteLine u\stream,txt$
		EndIf
	Next
End Function

Function SendUserMessage(txt1$,txt2$)
	For u.user=Each user
		If u\stream
			WriteLine u\stream,"[USER]"
			WriteLine u\stream,txt1$
			WriteLine u\stream,txt2$
		EndIf
	Next
End Function

Function DeleteUser(tstream)
	For u.user=Each user
		If u\stream=tstream Then
			Delete u
			Exit
		EndIf
	Next
End Function

I get a MAV error on Next in the main loop. I marked it.

Did you check your recycling bin?

Yes. But I deleted the original about 2 months ago.
