$and and $or fail to return true when they should.
Help says: $and(x,y) returns true, if x and y are true (not 0 and not empty).
but from "$and(1,1)" expected "true", got "".
and from "$or(1,1)" expected "true", got "".
That's from the following Export script:
Help says: '$and(x,y) returns true, if x and y are true (not 0 and not empty).'
but from "'$and(1,1)'" expected "true", got "$and(1,1)".
and from "'$or(1,1)'" expected "true", got "$or(1,1)".
