Foreach Loop Containet problem in SSIS

I am trying t o use Foreach Loop container (Foreach Item Enumerator) to do some tasks with each table on the list. I entered the list of all table names I want to work with. I created the variable to hold the table name. I add execute sql task in the container.  I map the paramenter to previously created variable. I want to use this parameter in SQL statement but I am always getting an error:
-"drop table @tblName" failed with the following error: "Parameter name is unrecognized.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

-[Execute SQL Task] Error: Executing the query ""drop table '"+ @[User::TblName]+''''" failed with the following error: "Incorrect syntax near '+'.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

This is just 2 examples of what type of error I am getting. Can you please let me know how to set up and use parameters the right way ?

Thank you
