Problems with mod creation

hi , sorry in advance if my english is not perfect.I try to make a mod in the editor , but the problem is the triggers do nothing , I can’t use it and I know it well done , because in normal map creation everything work well , but does I need to do something to activate triggers in a mod creation ? I already had this problem in the past and I find the problem but its a long time ago and I dont remember what i did to activate the triggers in mod creation.

You need to create trigger library.

tx tangor , but i found the problem , it was the library id , i had an other library that had the same id code and that made it block and impossible to load when the map started. p.s tx again for your answer
