Two things.

1. you generally want to divorce type declarations and variable 
declarations.

2. It looks like you might be declaring storeInfo as local to a 
function. You can't use a local type declaration as a template param.

try:

struct storeInfo {
 // ...
};

storeInfo structInfo;

void f()
{
stack<storeInfo> itStack;

}
