PMFJI,

I am slightly mystified by how the whole init thing works. One would assume that the container doesn't exist until all it's children have instanciated and the containers init has fired (if I look in the debugger while stepping through the init sequence the parent is not there). But it doesn't work that way.

Tom can do what he was attempting, I think the syntax was wrong though, it should be

IF PEMSTATUS(This.Parent.Parent, <b>'DisplayValue'</b>, 5)
  added code here
ENDIF

This will return true if the grandparent contains the PEM from this.init. I tested and does work. But I would think it shouldn't for the same reason Tom stated, 'The form has instanciated'.

Care to DeMystify this behaviour?
