If you try to run the procedure directly by pressing F2, you get the error message shown.

Figure 1. Mismatched parameters error message

This error message appears because the procedure expects parameters and you are not passing it any when you just run it from the editor. However, you can check whether your syntax is valid by pressing SHIFT+F2 or selecting Compile > Check Syntax from the menu. The information box shown appears.

Figure 2. Correct syntax information box

After you verify that the syntax is correct, continue on to write the code that calls the procedure.
