Mrinalini - When I log onto Amazon.com, i'm taken to the U.S. site since that's where I live. You'll have to log onto Amazon and see if there's an Affiliate program in your country.
If so, sign up for it and make sure you add your affiliate ID in the settings of your Wizzley profile. If it's not there, Amazon won't be able to pay you.
If the Amazon affiliate program is not available in your county, you may want to try Viglink (there's a lot of information on this program on Wizzley), or see if you can sign up for Google Adsense. Again, don't forget to add your program IDs to Wizzley or you won't get paid.
Getting back to Amazon, if you're an Associate, you can add Amazon products to any new or any existing pages - just use the Amazon module. Just remember that when you edit an existing page, you're editing in real time, so make sure you have the module products the way you want them before you click on "save." If you're working on a new page, then nothing goes live until you click on "publish." People have to BUY a product, not just click on a link. Amazon commissions are not high, but you'll get paid for everything someone buys even if it's not the product you promoted (as long as they went through your link).
