Mix together the pretzels, brown sugar, and melted butter. Press into a 9x13 dish.
Bake at 400 degrees 13 minutes. Remove from the oven and cool completely.
Beat the cream cheese and sugar until fluffy. About 4 minutes. Add the cool whip and mix another minute.
Heat the water in the microwave until boiling. Stir in the Jello until dissolved. Put in the fridge and let it get a thick. Add the berries and let it set some more, but not completely.
Spread the cream cheese mixture over the crust. Top with the Jello. Cover and chill about 3-4 hours until set.
