Matrix Header Object Name

I seem to recall that when named matrix frame/header/corner objects are needed there are naming conventions for the objects that must be followed for the header to display correctly. I cannot for the life of me seem to find the relevant discussion in the Help nor in the Forum. Can anyone steer me in the right direction? Thanks!

You don’t need a name unless you have multiple matrixes on a single form.

If you have multiple matrixes on a form, each must be named. There is no naming convention, they simply have to be unique. This is discussed on the page linked above.

For header/corner objects, see this help page.
