Unable to get spot lights working in vray

Hi, I’m a newbie to Vray (and have watched a few tutorials looking for the answer to my problem) - but I can’t seem to get my spotlights to turn on. Rectangular, sphere & dome lights work fine.

LInk to screen shot:

You may need to turn the intensity a lot higher than you expected.

Ha - yes, I just found my problem (I was turning up the intensity on the wrong spotlight).

Thank you
