Have you looked up Calling Procedures in a Subform or Subreport - the syntax is roughly the same.

Also, modules in Access 95++ are class modules, so you can add custom (public) methods, etc. See Custom Methods and Properties in the help file.

In a form, declare a subroutine...

public sub test
msgBox("Wibble wibble...")
end sub

In your code (assuming your form is called TEST):-

Forms![TEST].test


(Apologies to all for answering an Access 97 Question in a VFP forum).
