I'm sorry. I thought I was explaining myself. I am open to ideas on this project because of having to access so many different shapefiles for the user I really didn't want to write a ten page program with If then statements. I have attached a picture of my GUI that I have now. Let me try to explain our work here at TxDOT. We have about 6 different count machines. And our customers (i.e. the public) want maps to see where we do traffic counts. Now, they may need a variety of different stations. So, they may want a map with manual stations on it or a map of manual stations and ATR stations or they may want a map of manual, ATR, and classification stations. So, the maps can have a variety of stations and not just one station. Please let me know if this still does not make any sense. I think the tab idea is a good one. Like one tab for the state and one tab for each district in the state. Then on each tab there would be a checkbox for all the stations they have to choose from and then they can pick which stations they want on their map. I've also attached a word document of the tab idea.
