disabling macro message

Hi There,

I created an excel sheet with some very basic VBA codes and many check boxes
and dropdown lists. Finally, I decided to remove all VBA and use check boxes
and dropdown lists from "Forms" tool bar.

After removing all checkboxes from "Control Toolbox" I enter VBA codes and
just deleted everything.

Now I am trying to "Exit Design Mode" (unclick) on "Control Toolbox", but
whenever I do this I message pops up "The macros in this project are
disabled. Please refer to the online help or documentation of the host
application to determine how to enable macros.".

I want to get rid of this message... is there any way?

Thanks in advance
