the previous code is not working: $\%$ Facts

shape$($conical$).$

shape$($flat$).$

shape$($bell$\_$shaped$).$

shape$($convex$).$

edible$($edible$).$

poisonous$($poisonous$).$

size$($small$).$

size$($large$).$

size$($medium$).$

color$($white$).$

color$($red$).$

color$($brown$).$

color$($yellow$).$

color$($red$\_$dotted$\_$with$\_$white$).$

$\%$ Rules

is$\_$edible$($Mushroom$)$ :$-$ size$($Mushroom$,$ small$),$ color$($Mushroom$,$ white$),$ shape$($Mushroom$,$ convex$).$

is$\_$poisonous$($Mushroom$)$ :$-$ size$($Mushroom$,$ large$),$ color$($Mushroom$,$ red$),$ shape$($Mushroom$,$ flat$).$

and it show this message error : Clauses of is$\_$poisonous$/1$ are not together in the source$-$file

Earlier definition at line $22$

Current predicate: is$\_$edible$/1$

Use :$-$ discontiguous is$\_$poisonous$/1.$ to suppress this message

procedure $`$size$($A$,$B$)\text{'}$ does not exist

Reachable from:

is$\_$edible$($A$).$ i need sompne to solve this problem for me please $...$
