One account with multiple contacts on vf page


we have one add account button and del button at time for page load 
When the user click on the add new account then few fields ex: Account name ,Industry and Rating are show with inputFields so the user can
enter the user value and then two more button are display on page to add the contact for that account and delete the contact for that account.
For example one account with multiple contact on row.I have try but actully i have used the two pageblocktable with the Map in which i receive the value in one pageblocktable but when i am using the contact value in pageblocktable it is given the error i.e Map key null not found in map.
I am sharing the code ...

<apex:page controller="Addcontactwrappernewcontroller">
 <apex:form >
   <apex:commandButton value="Add Account" action="{!addaccount}" rerender="panel"/>
    <apex:pageBlock >
