Take out the two lines:
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;
Then compile your program - you will get errors.
GO to the first error - probably on the line:
ReportDocument cryRpt = new ReportDocument();
and put the cursor in the first word that is underlined in red. A small blue box will appear at the beginning of the word. Hover the mouse over the box, and a dropdown will appear. Open the drop down, and it will have possible solutions to the problem. The first one should be "using ..." select it and it will add the using statement for you. Repeat this until your references are correct.
