Thread: amendment

I am trying to translate amendment in the following context:
"Before leaving for the Commons, Andrew checked over an amendment he wanted to move in comitee that morning"

((Andrew is a MP))

my attempt:
"Antes de dirigirse a la Cámara de los Comunes, Andrew revisó un proyecto de ley que quería presentar al comite esa mañana"

Please correct my version and give me your oppinions.

Thanks!
