Making a Scenario Pivot Table in Scenario Manager Issue

I'm a student working on my final Excel assignment. Here is what I've done so far:

I created three scenarios in Scenario Manager
I selected one of the scenarios and created a Scenario Summary Report
I deleted a few rows and columns as instructed in the assignment

The final step is to create a Scenario Pivot Table Report. The instructions say, "In Scenario Manager, select Summary and then make sure Scenario Pivot Table Report is selected."

However, when I opened Scenario Manager, none of the scenarios are listed and the Summary button is greyed out so I am unable to create the Report.

Does anyone know what is wrong? Am I missing something?

Thanks in advance for any tips or advice

I was able to solve the problem by navigating to the Worksheet that contained the Scenario data. Then, the scenarios repopulated in Scenario Manager, the Summary button was available, and I was able to create the Pivot Table Report.
