Computer Craft error coding

[knightofe2]

I coded a email system for my server for fun but I cant figure out why i keep getting this issue. also I only get this error when I read an email not when I send it out to the server

server:11: Expected string

    print("Running eMail server")

    rednet.open("right")

    while true do

    id, message = rednet.receive()

    if fs.exists(id .. message) then

    mail = fs.open(id .. message, "r")

    print("Computer " .. id .. " read his mail number " .. message)

    readmail = mail.readAll()

    rednet.broadcast(readmail)

    mail.close()

    fs.delete(id)

    else if message == "sendmail" then

    id1, to = rednet.receive()

    a = 1

    while fs.exists(to .. a) do

    a = a + 1

    end

    mail = fs.open(to .. a, "w")

      mail.writeLine("Total Amount of Emails: " .. a)

    if id == 1 then

        mail.writeLine("From: ArestheBloodGod")

        elseif id == 2 then

        mail.writeLine("From: Knightofe2")

        else

    mail.writeLine("From: " .. id)

    end

    if to == "1" then

        mail.writeLine("To: ArestheBloodGod")

        elseif to == "2" then

        mail.writeLine("To: Knightofe2")

    else

        mail.writeLine("To: " .. to)

    end

    id2, tm = rednet.receive()

    mail.write

    mail.close()

    print("Computer " .. id .. " sent Mail to " .. to)

    end

    end

    end

p.s. I do not take credit for this code I edited it from someone else

On Line 11, it says "fs.delete(id)", which is giving you an error because "id" is a number, not a string. It's possible you meant to put "id .. message" to delete the message after you send it, but If you really meant id, you could do tostring(id), I beleive.

That sounds awesome! Are you able to just copy and paste the code?
