So, I am sure I am missing something obvious and I will apologize in advance for this...

I am using Joomla 1.5.26 with VirtueMart 1.1.9 and MetaMod 2.12.

All I want to do is to prevent certain modules from appearing anywhere in VirtueMart.  Otherwise, I want the normal module display parameters to work as usual (as controlled in the module manager). 

For example, I put in this "rule" since I do not use the "VirtueMart FrontPage" I figured that it would eliminate display of the modules by default...:

$vm = JomGenius("virtuemart");
if ( $vm->check( "pagetype = frontpage" ) ) return 115;
if ( $vm->check( "pagetype = frontpage" ) ) return 119;
if ( $vm->check( "pagetype = frontpage" ) ) return 56;

but it only seems to stop module 56 from being displayed--and even then it is not consistent.  For example, module 56 displays on category pages, but not product details pages. 

Thanks in advance... I've been reading this forum for over an hour and I need to get this done...
