I just did a search for postings by you and see you've been asking this question for a bit over a month (and I answered last time too). I'm going to assume that you are new to Domino/Notes. I don't know if you're new to app development.
When you submit a new post to this forum, there's a link at the top of the page to the FAQs. There are several great FAQs that can help you get started doing Notes development. The FAQ of FAQs also includes links to some good development sources.
If this is something you have time to learn and are not under any pressure to get something built, you're in good shape. Just start with something very simple, break it down into bits, search around for tips/hints, and learn how to do design work in Notes/Domino.
Use the Search feature in the forum. Use it in the 4/5 forum. Whatever you want to know, I can almost guarantee someone has asked the question before and the answer is available.
Use designer help - it is awesome.
If you're writing lotus Script, use the debugger.
If you're writing @Functions, use @Prompts or @StatusBar to display intermediate variables so you can debug your code.
Start small, build as you go. If you try and build everything at once, you'll fail.
If you're into Java, Bob Balaban (who knows just a tiny bit about Notes) is now releasing his Domino/Java book for free. It's probably one of the best books ever written for Domino and Java so go grab the chapters as he posts them.
If you need to bring up a mission critical app quickly, I'd recommend you A) Get some formal training and B) Buy a consultant to help you get the first app out there working correctly. You'll do your organization a disservice if you release an important app and it doesn't work.
