Are possible to make function, that checks file info (Vehicle owner file) and returns Id's of that file
For example:
vehicle owners file:
1=Sunshine Autos
2=Jancis
3=Jancis
4=Sunshine Autos
Function will return numbers, where is write Jancis, and that will be in list like: 2,3
I hope you something understand, i don't speak english very well.
