[Lua][Question] Bundled Cables input?

I have found out that I can use BundledCables to controll something. So how to get the input? I used this (found out in help redpower):


c = rs.getBundledInput( "right" )
red = colors.test( c, colors.red )

And I tried this:


c = rs.getBundledInput("right")
red = colors.test(c, colors.red)

But it throw error At line 1. What is wrong? Help me!

Try using rs.testBundledInput("right", colors.red)

Thanks, it works.
