Case Description:

I want to create a report & a subsequent dashboard that will show the no of days since last log in. Hence please let me know how to create a field showing " No . of days since last log in ". What is the formula to calculate " No . of days since last log in ".

I'm tasked with creating an Opportunity Amount field Trigger to Roll-Up from Opportunity Products. How would I go about creating this trigger to roll up from Opportunity Products? Sample code would be awesome!

Sincerely,
Junior Developer!
