Identifying the DialogBox in firefor

[MahalakshmiDevi]

The str would return "firefox 1.1". on execution of the code

Code:

Browser("micClass:=Browser").Page("micClass:=Page").Dialog("micClass:=Dialog").WebButton("OK").click

The error is displayed as "WebButton" cannot be identified and check the parent class.
Let me know whether the above code is right or wrong?where i have done the mistake.

-Thanks
