Hi Eric
thank you for fast answer
... so FET cannot do everything !! :)
Not sure about InlineJavascriptPlugin process
I have installed/activated the plugin
I have pasted your code in
[[Last5CreatedSliceAverage]]
<script>
> var count=0, total=0;
> // get ALL tiddlers, sorted by creation date (newest first)
> var tids=store.sortTiddlers(store.getTiddlers(),"-created");

Then I try to call it :
[[ConfusedVectorError]]

Am I mistaken in the process of using InlineJavascriptPlugin ?
