Create Simple Module for Zurmo CRM

Hi Folks, We have a basic Excel sheet that has about 6 columns, and it calculates some totals up the top. Wanting to create this as a module in ZURMO CRM. [login to view URL] Yurmo, is PHP/MYSQL using the yii framework. Up the top of the listings page it should show the totals for the months / qtr / year based on the renewal date and Renewal Amount ($) The module is for tracking 'Hosting Accounts', so there is about 4-6 top level columns: - Client (Link to client in zurmo) - Website URL - Website Type - Which Server - Renewal Date - Renewal Amount Then a sub table for each of these records which wil contain the passwords etc: - URL - Login (These will need to be encrypted) - Password (These will need to be encrypted) Thanks
