Where and how to use Modules?

[Guest]

I inherited a database using the calendar year. I need to change Jan. 1 to
Apr. 1
Ed Warren wrote a module for another poster and I copied it.
Now where do I use it? Tables, Queries, etc. and how? From what I read it
has to be used as an Expression. ????
Please help

This is not an answer to the question you asked.

But if you need to change an existing value in a Table - research the topic
of an "Update Query" on the Access web site. This may be another way to do
it - you may find it easier than working with a Module.
