Open up multiple copies of a form

I have a form called Contact, but I want to open several copies of each form from clicking on commands from other forms (so could have 6 open forms up, all referencing different records.

I managed to open one form, but when I was on another form the first open instance was closed and the new one opened up, I want to keep the old one open and open a new. I managed to open one by:-

DoCmd.OpenForm "Contact", acNormal, , "ContactId = '" & ContactId & "'", acFormEdit, acWindowNormal

Select allOpen in new window

After reading about I managed to find an example code of:-

    Set frmMulti = New Form_Contact
    frmMulti.SetFocus

Select allOpen in new window

But it doesnt work at all, and cant see anyway of filtering the record.

Any ideas?
