need some help with an automated dice roller script

I am self taught with html, and i was wonderting if any of you could help me out.

I'm trying to crea a dice rolling script that will input a command directly into an irc script. The irc script is PJIRC if that makes any difference.* I'm using the following code

<b>A:* </b>
<b>B:* </b>
<b>C: </b>
