I am very new to Zoho creator.   Can any body help to find  books / videos to learn advanced functionalities in Zoho creator ? Currently I am looking for an answer to following points.

1. How do I create an Invoice Print to suit my pre-printed stationary ?

2. I have a master record of customers for whom equipment are sold.  For each services done Job card is maintained in another table.  I need to update the last service done date in master table.  Is it something complicated to achieve in Zoho creator ?

Please help.

Regards,

Jay
