I had a compile error on saving the Advanced PDF Here is the line it refers to, but there is no <td> referenced in there. The rest of the doc does have some but they all 'open' and 'close' correctly. Any thoughts?

<th align="left" colspan="3">Part No.</th>

The <th> element is effectively a <td> element but used as a table header. See https://developer.mozilla.org/en-US/docs/Web/HTML/Element/thead. However, I have found that the line numbering in the Save functionality in the editor often gives me a completely wrong number offset from the real problem, so it might be referring to a different line. You might be able to find this offset by putting a bad tag at the top line after <pdf> and see what line number it gives you. That is more likely than the line you showed being the actual problem.
