Hi everyone!

I would like to know how it is possible to change the values shown in a SubForm wich have its own SQL definition, ir order to take the Initial Date and Final Date that are in a textbox in the form.
Making a button to perform this change is easy but...¿How to implement that behaviour?

Typical usage of Form/subform construct is when tables involved have a 1 to Many relationship. For instance, 1 Student takes Many Courses. Student is the recordsource for the Form, Course is the related data in the subform and the link fields in the forms is StudentID.

What exactly are the tables involved in your set up?
I'm not following where Initial Date and Final Date fit and what they apply to.
