This is commonly known as an “indexed-repeat error.” It occurs when a field that is inside a repeat group is directly referenced from outside that repeat group.
This error means that somewhere in your form definition you have referred to a field that does not actually exist as a field in your form.
You have received this error because the total number of begin group/begin repeat rows in your form does not match the total number of end group/end repeat rows.
You have a calculate, relevance, or constraint expression that has a syntax error that makes the expression incorrect.
