I want to build a sophisticated form that tracks a user through 20 different visits, modifying some of the form and instructions based upon the visit number he/she is on. Also the form should automatically generate reports/graphs from the data gathered on specific visits. IDEALLY, certain button actions of the form can 1- open a program that is installed natively on the user's computer (is this possible)? 2- allow for the import of .txt files from user's computer, convert and graph. We have a complete working EXCEL version of this solution, having used VBA to automate, which we've run for years. So the specs are very detailed and clear to communicate through a demo. What we want is to make our present solution password protected and online deliverable.
