Which MacBook Pro model do you have? If you're selling it, you have to sell it with the version of OS X that shipped with it, not a version of OS X that you later purchased. See Thomas Reed's - How to prepare your Mac for sale.

thanks for the quick reply.. seems as this is the problem that I have updated to mountain lion. I will need to find the cds that cme with the computer. If I dont find them is there any solution?

With your serial number handy, you can order a set of machine-specific DVDs from Apple. Cost is about $20USD + shipping and taxes. You really do need this set to pass on to the buyer, just in case they ever need to recover the machine. The new owner can always upgrade the OS should they choose with their own Apple ID.

When I click on Reinstall Mac OS X Lion, it says "A server with the specified hostname could not be found." Then it takes me back to the original menu. I need to reset the computer, will it work still!
