Invalid object name when creating a stored procedure

I am trying to create a stored procedure on SQL Server 2008. Whenever I try to execute the procedure, I get an invalid object name error in the #EDPTS table. Can someone please take a look at the below code to let me know what might be causing the problem? Thank you in advance

use maindb
go
