I am new to qtp and this is a sample script in which I am facing a few errors like "URL might be wrong".

```
Browser ("Google").Navigate ( "http://www.google.com")
Browser ("Google"). Page ("Google").Sync
Browser ("Google"). Page("Google").  WebEdit("q:"). Set (" tarun lalwani")
Browser ("Google") .Page  ("Google"). WebButton ("Google Search").Click
Browser ("Google") .Page (" tarun lalwani - Google").link ("knowledgeInbox").Click
Browser ("Google").Page ("knowledgeInbox").Sync
Browser ("Google") .close 

```

What is going wrong?
