TSNgaihte,
In your rules you have that continuers should occur in the following places:
p p/q1 b/q1. This means that you should have a continuer every time there is a new \p or if there is a \q1 following a \p or a \b.
In this text you have a quote that starts in the \p. Then you have a second level quote that begins in the \q1. Since your rules says you need a continuer for a \q1 that follows a \p the error message tells you that a continuer is missing in verse 17.
You should have:
\q1 << <Inn kasak…
Notice that I’ve put a space after the << so that it is clear that this is the continuer.
As KimB notes, you must decide if this is in fact the rule you want to use. If you aren’t normally using the continuer in this case then you might need to change your rule.
