i'm stuck at a point where i'm not sure what combination of if / route / gate / select objects i should use.
i have 2 variables: theta1, theta2
and 4 other variables: a, b, c, d
i want some kind of 'filter' that says:
if either 'a' or 'b' are equal to zero, then pass on "theta1"
if neither 'a' or 'b' are equal to zero, then compare 'c' and 'd'.
if c>d then pass on "theta1".
