i wand to convert a number like 120 to one Hundred Twenty.

but i dont want to  use javascript in my apexcode to print any number.

please help me as soon as posible.

I am trying to grab the date value from a custom Object and use that value to date range another query. Here is my code:

Date startDate = Date.valueof([Select startdate__c From Custom__c ]);

I do use a where clause to return just one value. StartDate__c is a date field on the Object.

This is then used in the following query:

Select OpportunityId From Opportunity Where Opportunity.CloseDate >= :startDate 

I get the following error:  Invalid date: common.apex.runtime.impl.SObjectList

any help?
