Would appreciate some help with this.

Yes, the error says you have added (or previously existed) xhtml tags that have an attribute called "dir" and that attribute if needed at all should only have one of two directions: ltr (text goes left to right) or rtl (text goes right to left). The 17 indicates the line number and 30 is the column number in that file to look at to see the problem attribute.

Unless you really have an ebook with text that reads right-to-left, I would remove that dir attribute completely for those tags.

This can be easily accomplished in CodeView

So you have code somewhere that looks along these lines:

<p>This is some <span dir="gibberish">invalid</span> code.</p>

If you get rid of the dir, you should get this:

<p>This is some <span>valid</span> code.</p>

Side Note: dir is used for saying if the text is left-to-right (like English), or right-to-left (like Hebrew).

But as KevinH said, it probably is best to just remove it unless you are writing Hebrew/Arabic.
