I have a computer sending stuff through rednet. It is in a table and I dont know to make it print all values. This is an example of what it would be sending.

{
  "smigger22",
  "jasperdekiller",
}

I have no code cos its midnight

You need to loop through the table.

if type(message) == "table" then
  for a,v in pairs(message) do
	print(v)
  end
end

This would print out, for your table
smigger22
jasperdekiller

Thats exactly what I done but it still returns table: a1b2c3d4

Then post your code so that I can point out your error.

I already know your error.

When you send your message, instead of sending the table, send this:
textutils.serialize(table)
Then when receiving it, do:
table=textutils.unserialize(table)

To explain this, you can only send strings over rednet. Serializing converts a table into a string, and unserializing converts a serialized table(string) into a table.
You CANNOT, however, send functions over rednet.

Rednet actually automatically serializes the message for you, so you do not have to.

It depends on which version of ComputerCraft you're using. Anything even half recent will indeed handle it for you.

smigger22 could be trying to capture the rednet_message event, or making a number of other mistakes. Can't really say for sure without seeing the code.
