I have created a contact form as a user control which inserts data into a database. The database content then needs to be loaded into a custom section of Umbraco V4.

Below is the start of my c# code.

[code]namespace FinancialServices.Umbraco.Extensibility
{
public class FormContactTreeLoader : ITree
{[/code]

The table in the database dbo.umbracoAppTree has two important fields treeHandlerAssembly and treeHandlerType. Below are the values I have in the table.

[code]treeHandlerAssembly = FinancialServices.Umbraco.Extensibility
treeHandlerType = FormContactTreeLoader[/code]

The code inside the class is identical to that which is available here.

When I go to my custom section the tree node Data is visible and then the first child node displays the following.

[code]
- data
|--- Click to edit this item Error
[/code]

Urgent help would be much appreciated, thanks in advance.
