but the problem is we are not able to use these attribute in the logic.hence it's impossible to qualify same
Please explain exactly what you mean by "not able to use these attributes." Where is it that you're trying to access the View Minutes, for example? Be as detailed as possible. It will help you get answers.
we have created a custom object which holds the Attendance Data over registration Object. we need certain way to use oppertunity name to pull this through conditions to set logic.
like: if Opportunity name =Opportunity D3 send email 1
else send email 2
or Opportunity name =Opportunity D3 or Opportunity D4
send email 4
Similar way we wanted to store the information like Opportunity Minute..
Looking forward for your response.
