[Lua][Error]Trying to send a table

I am trying to send a table using rednet.broadcast(). But when I try to send it i always get the error message "rednet:327: string expected". My code is below.

local title = read()
  title = title..".txt"
  local h = fs.open(title, "r")
  local data = h.readAll()
  local table = {title,data}
  local msg = textutils.serialize(table)
  rednet.open("right")
  rednet.broadcast(msg)
  rednet.close()

Did you check rednet line 327? if type( sSide ) ~= "string" then…

rednet.close("right")

Also as a side note don't forget to close the file handle.

h.close()

The problem didnt occur anymore as soon as i changed

rednet.close()

to

rednet.close("right")

Thanks for reminding me to close my file handle too.

You should generally avoid naming variables (even locally) using certain identifiers that are already in use by the system. The identifier table is one such, and a pretty important one at that.
