Adding custom configuration section to existing tab

Question

Synopsis

I have created a basic local module that is designed to listen to an observer , which it does perfectly fine. However I wish the observer method to pull out some configured settings which changes the behaviour of it's task.

I want to add a new section under the Catalog tab; I found this question.

I do not want to create a new tab, instead I do want a new section under the existing Catalog tab (similarly to Catalog > Inventory).

Current behaviour

Currently inside the control panel I click Catalog > Catalog, low and behold inside this tab is a group called Section Name Under Catalog Tab. I also don't see my group Group Name.

• Image example #1
• Image example #2

Expected behaviour

I click Catalog > Section Name Under Catalog Tab, inside this tab is a group called Group Name with my enable/disable field.

• As per Image example 1 - I'd expect a section called Section Name Under Catalog Tab;
• As per Image example 2 - I'd expect this to expand into a view with my group Group Name;
• Finally the group should contain the form present in Image exmaple 2.

Conclusion

I've solved this and there were a couple of confusing aspects. Some of the XML tag names were incorrect and the module reference too was invalid.

In case someone else gets the same issue, I will wrap this up.
