Ok, so the title seems a bit confusing, allow me to explain:
If you have notifications, the variable "{vb:raw notifications_total}" will equal the total you have, (1,2,3,4 etc)
If you have none, you'd expect it to be zero, but for some reason it's blank? This seems like an oversight to me, I have to really out stretch my conditional statements to check if the var exists, then write in a zero manually, whereas I could just put the var in.
