Hi I need to make a table on an opportunity page layout for forcasting. I want the table to have 3 columns (1 year,2 month, 3 amount) I want the year and month to be determned based on the close date of the opportunity and automatically populated. then the user adds the amount any ideas?

I use Constant Contact for email marketing. I have integrated constant contact to display in a contact view in the field, "Campaign History." It has been working for over a year. All of a sudden it is no longer displaying properly. I have attached an image of what visual force is now displaying the field. 



Error code from scrolling:
only whitespace content allowed before start tag and not E (position: START_DOCUMENT seen E... @1:1)
Error is in expression '{!FetchNextSummary}' in page ctct21:contactcampaignhistory: (CTCT21)

If you have an idea of what may be causing an error, that would be extremely helpful.
