Also refactor out concerns in your code. It will help you bug hunt faster
too. For example, I would personally pull this out of SumField:
var checkTiddler = $tw.wiki.getTiddler(storeTiddler);
if(checkTiddler && storeField) {
output = String(output);
if(output != checkTiddler.getFieldString(storeField)) {
$tw.wiki.setText(storeTiddler,storeField,storeIndex,output);
}
}
This has nothing to do with summing fields and it is a rather pivotal
point in you code where a problem like yours might be arising. Separate it
out and you can even mock it to see if it is behaving as it should.
Sorry I edited my post and it took a long time so I don't want this advice
to be overlooked.
