User modification (radio Button)
this will give me fields applicable to modify a user account
this can be in the form of a new page or hide or unhide certain field.
You will need to have 2 subforms. When you click the radio button, it will hide one of the subforms and show the other. By default, the forms would both be hidden. In the java script for the "change" event of the radio-button, hide one and show the other. Below should help you get started.
"New User" selected:
"Existing User" selected:
Java for radio-button change event:
form1.frmMain.frmNewUser.presence = "visible";
form1.frmMain.frmExistingUser.presence = "hidden";
form1.frmMain.frmNewUser.presence = "hidden";
form1.frmMain.frmExistingUser.presence = "visible";
