Trigger an Event when a Correct Message is Sent?

So, I was trying to trigger an even (in this case,

print("Correct")

and

print(rec)

) but for some reason it triggers that the message isn't correct even when I broadcast the correct message. Can someone help me out? Thanks.

rednet.open("left)
rec = rednet.receive()
if rec == "Test" then
print("Correct")
print(rec)
else
print("Incorrect")
print(rec)
end

Thanks in advance!

EDIT: I took a look at the output and I found out that the computer had just sent it's own ID? I used the following in the Lua console:

rednet.broadcast("Test")

Take a look at the wiki page for rednet.receive, you'll notice what it returns.

Oh, that makes sense now. Thank you!
