Hello and Welcome to UA!!!
If the form's all have the exact same layout but you want them to only able to view their own data, you will need to assocaite each record in the database with the person. One of the easiest ways would be to add a field which will hold a user id or something that is unique to each user. You can use an API to
Get Login name of the user on the network or create your own login procedure like
this one from the code archive. HTH.
