You guys still have some work to do on being able to set up multiple menus which interact together in a database type format. 
This is an old example, but one which I've used for a lot of different things over time. Here we generate a 2-field database (Name and Age), and it displays both of those fields. You can link those fields together and use one of control the other (sort by age and the names change to match your sorting), or you can break them apart and only work in one without regard to what the other displays (for completely independent lists).
As far as most menu type things go for me, this type of routine is one that I tend to plug in and make a use of a *lot* for my personal work. For example, I might have an MP3 player which contains the following information:
Song Name -- Artist -- Length -- Format -- Drive Location
Just zap it into the above and now I can display and sort and scroll by any of those fields as I desire, and click on whatever file/field I want, with just a scroll/click of the button.

This is an old example, but one which I've used for a lot of different things over time. Here we generate a 2-field database (Name and Age), and it displays both of those fields. You can link those fields together and use one of control the other (sort by age and the names change to match your sorting), or you can break them apart and only work in one without regard to what the other displays (for completely independent lists).
As far as most menu type things go for me, this type of routine is one that I tend to plug in and make a use of a *lot* for my personal work. For example, I might have an MP3 player which contains the following information:
Song Name -- Artist -- Length -- Format -- Drive Location
Just zap it into the above and now I can display and sort and scroll by any of those fields as I desire, and click on whatever file/field I want, with just a scroll/click of the button.
