Newbie has problems...

Hello,

I'm totally new in Prolog and I use BProlog. I get some errors ("Predeifined
predicate is redefined") with the following code:

hall_wet.
bathroom_dry.
window_closed.

leak_in_bathroom :=
hall_wet,
kitchen_dry.

problem_in_kitchen :=
hall_wet,
bathroom_dry.

no_water_from_outside :=
window_closed
;
no_rain.

leak_in_kitchen :=
problem_in_kitchen,
no_water_from_outside.

What's wrong???

Sorry, it was a typing error. Of course I have to use ":-" instead of
":="... Now it works fine...
