This functionality works fine on my version. Can you please take screenshots of each point you input some data into the wizard please?
Also if you look at the bottom of the app, there are links entitled ReadyAPI log, HTTP log, Error log, etc. If you can provide the ReadyAPI and Error logs that detail should be enough to enable people to help diagnose the issue.
if this helped answer the post, could you please mark it as 'solved'? Also if you consider whether the title of your post is relevant? Perhaps if the post is solved, it might make sense to update the Subject header field of the post to something more descriptive? This will help people when searching for problems. Ta
