Comparator Error

[olegrz]

Hi, I'm trying to realize logical implication function by means of the "Greater than" block - see attached screen copy.
In Error Log screen I obtain th following message:
---------
Library custom/fbeditor20/Comparator:0: attempt to compare two boolean values
stack traceback:
Library custom/fbeditor20/Comparator: in function 'fbe_greater'
---------
How to resolve this situation& Thank you in advance! KR Oleg
