The Dynamic ComboBox Challenge

I have a challenge for someone to work out for me. :smiley:

Im making a site that im trying to make as dynamic as possible.

The movie is set out like this: Only one comboBox and one Dynamic text field.

I want Text to load into the dynamic text field dependant on the selected field. But thats the easy part!

This is the hard part. I want up to 5 fields in the ComboBox dynamically loaded from an external .txt file. Then when a certain option is selected from the comboBox, it loads a section of text from another external .txt file.

Now to picture this better: It is being used as a gig guide for a band site. When a Date is selected in the comboBox it brings up the gig info in the Dynamic Text Field. All the info needs to be changed easily over one or two text files.

Many thanks in advance.
