[Plugin: Posts per cat] displaying only posts from a page

Hello,

Love your plugin.
Though I need to restrict posts from all appearing and only wanting posts from a particular page appearing.
go to: gotoneminute.com and select a category and you will see what I mean.

I need to show only posts from that category.

Any suggestions?

thanks in advance,

gom
