How to use Excel Macro

For a project work I need to build up a macro. The thing is that I had never done this before, so for the starting point this has become really hard to understand. Friends say that doing this by vba is much better and easier job. I want to build up a macro that can provide a form fillup and then total of some amount at the end. I tried to use the same by reading the help file. But nothing much helped here. Sometime nothing happens there. I tried following the keys combination of ctrl + b but there is a error popup on the screen. It is better to have some sample on this. Thanks.
