This trigger is designed to count activities on a lead, like # of calls, # of emails, etc. The code works well, but I can't for the life of me seem to be able to create a test class that gets sufficient code coverage. I get like 9% code coverage by creating a lead and creating a task in my test code. PLEASE SHOW ME HOW IT'S DONE if you would, please.

Community, I hope you can help me. I'm stumped. 

I'm the Salesforce admin at our company and I have created a dashboard full of reports with the interntion of packaging that all up and sharing it with our customers. However, once I have packaged up the dashboard, reports and custom fields assciated with the reports, I tested this package first by installing it into another Salesforce account, but the reports do not work... at all.

Just to give you more information, here is the dashboard in our primary SFDC account (which works perfectly)... 


On an individual report level, I use Joined Reports and the "assigned" field as the cross-block grouping field...


However, once I have installed the package in another SFDC account (which is essentially a mirror of our main account), the dashboard is blank...


... and my reports are now MISSING the "assigned" grouping field...


I can't even add the "assigned" field back in... it's actually there, it's just invisible and completely inaccessible. I know it's there because when I edit my chart, it still shows "assigned" as the Y-axis...


But it's straight-up NOT working. 

PLEASE help :-)
