Dependent Combobox Userform

Hi Guys,

I am currently running VBA when ComboBox1 is selected ComboBox2 shows specific information based on lists in the spreadsheet.

Now I would like it if ComboBox2 showed "Business Improvement" then ComboBox3 will show information set in that list.

Also, my submit button isn't working and I can't find out what's wrong using the debugger

I've attached the spreadsheet as the lists will make more sense and hopefully you can help me.

Thanks in advance.

Frank
