Finally found the issue, and yes - I feel like an idiot.

Apparently, while trying various things I inadvertently capitalized the 'I' in 'If' and no one (including me) that was looking at it caught it for quite a while. Once I un-capitalized it, it worked exactly as it should. javascript - case insensitive, 'til it's not.

>>>Yep. The 'If' is a problem. This should work:
function SCDropDown(topiclist)
>>>        {
>>>            if (topiclist.selectedIndex > 0)
>>>            {
>>>                location.href='go.hcn?hcn2~recipe~'+topiclist.options[topiclist.selectedIndex].value;
>>>            }
>>>        else {
>>>                alert('Please select a recipe');
>>>            }
>>>        }
