[attempt to call nil] immibis peripheral

right now im working on a program to write code to an rfid from immibis periherals but im getting attempt to call nil on line 7

print ("enter name")
write ("name:")
local name = read()
local writer = peripheral.wrap ("top")
print ("insert your rfid for formatting")
while true do
local check = writer.getPresent()
if check == true then break
end
end
writer.encode (name, name"'s rfid")

thanks in advance!! :)/>/>

I think it's getProgress() or isPresent(), not getPresent() :)/>/>

thank you for answering my question and making me feel stupid :)/>/>
