Sage CRM 7.2: How to hide or remove 'Opportunity Total' panel from Opportunity Screen

Hi,

I have some trouble here. I'm not sure whether this question had been posted but I tried to search for it and I found nothing.

From our client's requirement, they would like to remove 'Opportunity Total' panel from Opportunity Screen.

I believe I saw some article mentioned that this kind of thing is very hard to do.

Dose anyone know how to do it? Any sample code will be really appreciate.

Thank you in advance.

Cheers,
