I'm a beginner to ZOHO Creator (and programming) and trying to understand the method of populating fields in a form (fetched from another form) based on a selection in a drop-down box. 

Let's say I have 2 forms;

- One"Golf_Bag" form with following information fields created; "Club", "Brand_of_club", "Model_of_club", "Loft_of_club".

- Another "Input_data" form with corresponding fields, and where "Club" is defined as relation to the "Club" in the Golf_Bag form and is selected in a drop-down box, 

When I select "Club" in the "Input_data" form I want the application to fetch the corresponding  info from the "Golf-Bag" form record and populate the fields in the "Input_data" form.

Most likely very simple to achieve but so far not possible to understand how to define.

Thanks
