.cwp to mp3??

Hi,

I'm a complete newcomer to all this. I have zero knowledge so please bare with me!

I've chopped up the songs I want to chop up and can save the file as .cwp but how do I make that mp3 or indeed anything playable?

When I try to save it as midi (I think) it says it contains digital audio (I have samples from movies in my file, does this make a difference?) and won't let me save as anything other than .cwp

Help, where am i going wrong?

Thank you in advance whoever replies!
