I am doing a UI mockup and want to have a worksheet where data gets inputed
and then when the user is ready submits the data by clicking a button. At
this point the macro checks that all required fields have data (will
constrain the type using built in excel data type constraints) and enters it
into table on another sheet. When it enters the data in the table it enters
a new record and it creates a unique ID number in the table based on the
previous entries int value incrementing by 1.

I am looking for a short and sweet solution to this, if you have samples or
can point me at good ones I would be very grateful.
