Windows Making an RPG [PROBLEM FIXED ]

hi! i'm currently making an RPG and when i established the movement, and solids collision, the firs room map and else,
was the time for a new room, so i created a second room, and when i created: the obj_next and obj_last (for tracking back to the previous room)
and go to the "step event" of obj_character.

(obviously the are other few variables but it's to much to read, this only matters)

obj_character goes like this:

STEP_EVENT:
///colission with obj_solid
if (instance_place (x+hort_veloc, y, obj_solid)) { hort_veloc = 0; }
if (instance_place (x, y+vert_veloc, obj_solid)) { vert_veloc = 0; }
else

contact = instance_place (x+hort_veloc, y, obj_solid);
if (contact) {
if (contact.colission == true) {
hort_veloc = 0;
}
}

by this far was perfect, no problem or errors but when i add the event to collide whit the obj_next


///go nxt room
permit = instance_place(x , y, obj_entry);
with (permit) {
if (room_exists (map)) {
other.thexit = thexit;
room_goto (map);
}
else
show_message ("error map bad: " + permit.map);
}

(also in the map the obj_next have creation code)
So i launch the game and this came out

Variable obj_entry.colission(100009, -2147483648) not set before reading it.
at gml_Object_character_obj_StepNormalEvent_4 (line 15) - if (contact) { if (contact.colission) vert_veloc = 0; }

only when i add this the game does not work.

if (contact.colision == true)

colission not set before reading it.

a typo or you didnt set the variable colission ;o)
i don't know what it is the probl...just came when i add the colission with obj_next. and i checked no typing erros and the variable is set

Please show where you are setting this variable in the obj_solid.
it was in the create event but on the Obj_character, obj_solid has no events added
and then in step event make all those scripts
but don't worry, i just change the way to perform the room change~
