command button to add new record on subform

[msmuzila]

I have a form that has a command button that when i press it, i want it
to add a new record to a subform within a subform within this form

3 forms:

frmFind - has command button
frmAdd_Disk - is subform of frmFind
frmDisk - is subform of frmAdd_Disk and is the form that i want to go
to the new record


or if there is a better way to do sub-subforms, please let me know.
