@tuanphan It worked :) .Thank you so much .One last question . If I have to do this for another page , for example 'celebrity' page, what changes i have to do with code ?Do i need to replace '.homepage' with '.celebrity' or what ?Thank you so much !!!

@Waqar629 Replace .homepage with Page ID. Each page will have different ID.
