Is it possible to get the 'Roll Up Summary field value' in the Master Detail Relationship on Detail page as well.

Basically to get a copy of 'Roll Up Summary value' in Detail page as well for a validation check. I would like to get via Point & Click using Formulas and not with any code. Is it possible? Is there any way?

I am getting a datatype error as below saying the fields datatype not valid for function when doing a simple syntax check Error: Formula result is data type (Object), incompatible with expected data type (true or false).

I just created a formula field on a child object which takes value from Roll-up summary field of Parent. So yes it is possible.

My Rollup summary and formula fields are of following type:

Rollup Summary Field: Count no of child records

Formula field : Number type

Formula: Account.countopportunities__c

I think there is some issue with formula you are creating. Sharing that could be helpful to solve your issue completely.
