Tollgate problem (solved)

[mikejazz]

Hi gents, here is my problem:
I just finished a map covering Normandy area in France including 3 new towns, companies, gas stations and so on. Hundreds of kilometers with some smal roads and highways. Obviously I got some problems with invisible walls, companies not working etc... but all is fine now excepted the tollgate. I copy an existing tollgate and place it on the highway, checked add_signs and use_semaphores but still not working...
the only thing i got with the console is " unknown tollgate type -1" however this tollgate works fine in other part of the DLC France.
Have a clue?
Many thanks in advance for the answers.
Michel.
edit: what an idiot i am, i forgot the two spheres (start & end)
Have a nice day, Michel.
