What's wrong with this line of code...

[George Handley]

Good afternoon Tom, and thank you for the rehash. I always thought I had command over these constructs, but I guess this was the first time I tried to use it on two time periods that would never resolve to true. The lion head code is now working fine, and just needs a little tweaking to minimise when it doesn’t have to be off due to the wind.

Best wishes,

George
