Hello,

Why make it parameterized?
You can simply use

SELECT * FROM contacts ;
    WHERE companyid = companies.companyid;
    INTO CURSOR cContacts

Now you can set your controlsource of the grid to cContacts.
In the activate of the contacts page you can set

Requery('cContacts')

or

YourGridRef.Requery()

Then it should work
