[maxmsp] Inputs on the subpatches

Hi

I'm a brand new baby with Max/MSP.  The manual and tutorials have been great with helping me negotiate most of my problems, but I have one thing I can't resolve.

I've patched two adc~ objects to a subpatch with two inlets.  When I run cables inside the subpatch from these inlets, they appear and work as signal cables.  However, when I save, quit and reload, they become ordinary Max data cables.

When I repatch them, the subpatch works fine.  But they always reset.  Why is this?
