first of all I apologize for my english...

I'm writing my thesis using Lyx 1.6.3 and I am occurred in a great problem: Lyx starts numbering the document from the first page while I need the first numbered page is the Introduction (actually page 5).
How I could resolve this? I read something about the use of \pagestyle but I cannot modify the source code from Lyx. Is there a folder where I can find a .txt version of my document that I could modify?
Thank you so much for the support
