This is a list of problems that are likely to be encountered:

• One of the lines went missing.Does this line contain anywhere an equals sign? If yes, then all instances of the equals sign should be replaced with {{=}}.

• I've applied bolding/italics to a phrase and now the formatting is all over the place.Any formatting should be applied separately to each word.

• I receive the error "Mismatch in the number of words".Interlinearised lines don't contain the same number of words. If this is intended, then consider filling the empty slots with {}. If this is not intended, then the following points might help track down the cause:
  • if formatting or a template is applied to a piece of text then this text is treated as a single word:
  • non-breaking spaces are not treated as word separators;
  • if a sequence of words is enclosed in {curly brackets} then it's treated as a single word.

• I receive the error "Unknown glossing abbreviation(s)".See above for details, but in short:
  • If this was not intended as a glossing abbreviation, enclose it in {{no gloss}}.
  • To set the meaning of one instance of a glossing abbreviation, format that instance with {{gcl}}, for example {{gcl|PF|perfective aspect}}.
  • If the abbreviation occurs several times within the same example then it might be easier to use the |abbreviations= parameter, for example: |abbreviations=PF:perfective aspect.
