I am looking for a means to have a text value result base on searching for the existance of any related records in another object that is the child in the lookup relationship.   That is not a Master-Detail Relationship, but a basic Lookup.  

It looks like the standard Clone button on the Opportunity only clones the fields that are part of the current page layout. Can anyone tell me if I'm correct in that assumption? I have fields on the Opportunity that I need to be cloned that are not part of the layout. Will I need to override the button in order to use the Apex clone method? Has anyone seen this or have any other solutions for this?

Thanks!
