Hi Friends Thanks in advance

I have created Visualforce page with Dynamic multiadd functionalty, I have given Field dependency picklist values but I am facing some issues like
• Field alignment missing
• save function is not working.
• in this page Name of Dealer is mandatory field.

<apex:page StandardController="Service_sheet__c" extensions="MultiAdd" id="thePage" sidebar="false">
