Good morning.
Well, I have looked at your search form and files. The main problem is that you have "" for the All field. The default value for the the All value should be ---.
What I would recommend doing is use the build_fancy_select_field mod to create your drop-down menu. If you do not use this mod, then in the form, you cannot use All. You would have to leave --- as the value. The fancy build select fields allows you to put values in your form, such as "Choose one of the following" or "Choose All".
The build_fancy_select_field routine can be placed in your html.pl file. If you are not using this mod yet and would like to, let me know and I will post the codes.
If you are using a text field for your Schools field, using the drop down menu will only allow you to use values you have entered. The best route is to use the build_select_field routine or build_fancy_select_field routine.
Does this make sense?
