Hidden VB Code module/macro/function
 

A coworker left the organization and left behind several workbooks. In one
of these workbooks, you select a month from a dropdown list box and it will
create a monthly calendar based on the month that you selected.

The issue is that I cannot find the code to make some needed changes. The
assigned macro is dropdown3_change. However, this is not found in the
project browser or object browser.

I know that I am overlooking something, but I do not know what is my next
steps to see this code.
