Random roll to guild channel

[CypSteel]

I am looking at writing a macro script that would broadcast a random number to a guild or customized channel. I tried this, but it doesn't work:

/script n = random(0,100); SendChatMessage ( "Random Number Is" n , "SAY")

Second question would be, can you format the color of outbound text? or is guild text locked at that green color?

Thanks in advance,
