Addresses first problem in issue 1592

Addresses first problem in issue 1592, removes an erroneous added $ from $false, to make it the constant false as was intended.

Hey Gina,
               I fixed this small bug to get used to the ThinkUp work flow. The bug was the first problem from issue 1592, to fix this I removed the '$' that was in front of the false on line 51
Thanks
Gareth.
