How to make a File Transfer program (line 10: attempt to call nil)

Hi Guys im trying to make a work room but i am having issues with making a file transfer. I want it to transfer the program file in the folder to the PC

Server:

term.clear()
rednet.open("top")
print("---------------")
print("Download Server")
print("---------------")
print()
print("Active.")
while true do
id, message = rednet.receive()
if message == "houseofkraft" then
   print("/houseofkraft/program >> WORK-PC")
   code = fs.open("/houseofkraft/program", "r")
   file = code.readAll()
   rednet.send(id, "filereceive", file)
end
end

Client:

term.clear()
term.setCursorPos(1,1)
print("Please swipe Smart Card")
mag = peripheral.wrap("right")
mag.setInsertCardLight(true)
p1, p2, p3 = os.pullEvent()
mag.setInsertCardLight(false)
if p2 == "houseofkraft" then
   term.clear()
   term.setCursorPos(1,1)
   print("Welcome houseofkraft!")
   print("Downloading files...")
   rednet.open("top")
   rednet.broadcast("houseofkraft")
   id, message, file = rednet.receive()
   if message == "filereceive" then
	  code = file.readAll()
	  textutils.slowPrint(code)
	  shell.run("mkdir", "/myWork")
	  shell.run("cd", "/myWork")
	  file2 = fs.open("program", "w")
	  file2.write(code)
	  file2.close()
   end
else
   term.clear()
   term.setCursorPos(1,1)
   print("Access Denied!")
   os.sleep(1)
   os.shutdown()
end

I am getting an error that says "line 10: attempt to call nil"
Which probably means im doing it wrong

EDIT: The client is getting the Error

Thank You!

Line 10 of which script? Neither of the ones you posted are calling functions on line 10 and therefore wouldn't throw that error.

The Client has the error

just to make sure there is no previous lines of code on the client, is line 10 term.setCursorPos(1, 1) ?
