Can't get it to work...

I can't get it to replace the teaser.

I'm using Wysiwyg API with Tiny MCE 3.2.

I have a Content Type 'Writing' with a cck text field called Summary.

I have ticked its box under Content Management > Content Teasers

I have turned off all caching and cleared the Views cache, (even though I'm not using one ... tho I was) - its just the default front page view, and its showing a couple of 'Writing's that are promoted to the front page.

And I've cleared by browsers cache.

It doesn't replace the teaser, I can see in Contemplates (which is turned off) out put 'Teaser Variables' of node->teaser is still the same first paragraph of my Body content, not my Summary content.

This module would be perfect for my uses, thank you for creating it and I hope you can help me get it working!
