  Its the "USER" in referencing your variable in the script, that's case sensitive. Should be "User::FinalTieOut" and not "USER::FinalTieOut"

Error message

exception has been thrown by the target of an invocation

Is a general error message that is shown when an exception is thrown by the script code. To read the main error message you can add a try catch clause into your code and use Dts.FireError() method to throw the real exception.

public void Main()

 try

 string strMessage = Dts.Variables["User::FinalTieOut"].Value.ToString();
 Messagebox.Show(strMessage);
 Dts.TaskResult = (int)ScriptResult.Success;

 catch(Exception ex)

 Dts.FireError(0,"An error occured", ex.Message,String.Empty, 0);
 Dts.TaskResult = (int)ScriptResult.Failure;

 

Variables names

Based on Using Variables in the Script Task - official documentation:

You add existing variables to the ReadOnlyVariables and ReadWriteVariables lists in the Script Task Editor to make them available to the custom script. Keep in mind that variable names are case-sensitive. Within the script, you access variables of both types through the Variables property of the Dts object. Use the Value property to read from and write to individual variables. The Script task transparently manages locking as the script reads and modifies the values of variables.

Just change USER::FinalTieOut to User::FinalTieOut and it will solves the issue.
