Apply Nested Styles Script not working for me anymore

Question

This was a script to apply nested styles directly to the text as character styles.It was supplied to me by someone on this forum to help make a file adaptable to an epub doc. It has worked fine for many months but now it does not. I am wondering if the cause is that I have added two nested styles in the paragraphs, where before there was only one. The paras. are currently set up with nested styles as follows:[none] up to En Space, italic through 5 sentences.                  I am using 5 sentences because I can't figure how to use a para. end as a limiter. I know this is confused but any help will be appreciated. Thanks

That looks like mine (and someone didn't follow my request on this page) :
