i will see what i can do but it gets a bit tricky
this should work:
http://vgmdb.net/search?q=$IsNull(<Catalog#>,<Album>,<Catalog#>)
Oh, thanks for the new formula Steven. Sorry, I should have known that a url query address embedded within a function could trip up MB's parser with respect to templates. Looking back at some of my other web link templates, I see half of them begins with $IsNull and the other half begins with the url query address properly. The latter obviously worked fine with right-click.
No need to change anything Steven. I see the light now. Thanks!
