Loading Options are used to control the behavior of the form as it loads. 


Auto-focus first field - This is used when you wish to place the entry focus into the first available field when the form loads. If you are creating an entry-based E-form then this is a good idea to turn on. If your form is mostly an informational or dashboard form then it is normally best to turn this off.


Hide Toolbar - This is normally used for dashboard forms. If you turn this on then the top toolbar will be removed and the form will take the entire screen. 


URL Lookup Fields - You can use the incoming URL variables to look for a Record match when the E-form loads. If you want to send out a URL for the E-form and have it associated with a specific Record, you can use this method. Specify the fields here (one per line) that you expect to be supplied via the URL. When they come in, the system will use those values to look up an existing Record. If it finds a match then the form will be associated with that Record so any data saved will go into that Record.
