I am trying to add scroll bars to a SuperBitmap Window that opens up
fine otherwise.  All I get are Gurus when I add the ptr to the linked
list of Gadgets with my 2 Proportional Gadgets (scrollbars) in it.
All I am doing currently is initializing the following data structures
and Opening the window as normal with its gadgetlist ptr pointing
to my myGadgetList as detailed below.

Structures I use:

struct PropInfo HScrollBar = {
 FREEHORIZ | AUOTKNOB,
 0,0,
 0XFFFF,0XFFFF,
 0,0,0,0,0,0};

{..LIKEWISE EXCEPT WITH FREEVERT FOR VScrollBar .. };

struct Gadget myGadgetList[] = {
{&myGadgetList[1],
 0,0,1024,10, /* size of super bitmap is 1024 wide */
 GADGHNONE | GADGBORDER | GRELBOTTOM,
 BOTTOMBORDER | RELVERIFY | GADGIMMEDIATE,
 PROPGADGET,
 NULL,
 NULL,
 NULL,
 0X0,
 (APTR)&HScrollBar,
 1,
 NULL},
{...Basically same for Vertical bar..};

Any ideas on what I am doing wrong?  I imagine I am not initializing 
a necessary structure or something.  Any help would be greatly
appreciated.

Thanks
