    1. COHi Aidan, what are you trying to do with this code? It looks like there are a few things wrong with it beyond the error.

    2. COThe error you are getting right now is caused by the fact that re.sub does substitutions of regular expression groups and something in the words your passing in is getting mistaken for references to those groups (which don't exist). This answer problem isn't much help to you though, I can probably give you a much more useful answer once I know what you intended the code to do :)

    3. COHi, actually it is asked by me. This code is basically extracting a part of q['display'] (that is type=1), and a few keywords (done in regex) were being searched on that qitem['value'] (which is a string), and highlight the word as BOLD if it is found using the regex.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
