Check existence of web objects on page

[eltee]

I have 10 Webedit and 2 Weblist fields in the web application page. I need QTP to

(a) Validate their existence on the page and if yes, check if they are greyed out (disabled)
(b) Compare the values against a global datasheet

Could you please help me write a generic function which can be used to do (a) and (b) for different web objects like WebEdit, WebList, Radiobutton etc?

Thanks a ton!
