Retrieve data from end user filled out form

Good Morning,

We are working on Web Designer version 8.0.2.

We have a custom form which allows end user to submit information like First Name, Last Name etc. The submit button calls a 'SaveChangesToPerson' call action which calls Save:Person (Save) that triggers 'Entities are reloaded with the load type interactive'.

Our understanding is that 'Entities are reloaded with the load type interactive' grabs user entered data from the form, we are trying to understand how it does so because we need to grab individual filed values from the form Eg First Name, Last Name and pass to our custom parameter.

We have tried looking if the end user filled values are stored in a collection but that is not the case. We have a single row collection called 'LocalVars' on the component. Can we store the values in that collection or directly pass them into a parameter?

The form is basically a copy of the VI_ObjectEdit_Person module.

Any suggestions would be appreciated.

Thank You
