Let’s suppose you have this XLSForm. On the survey sheet, you have:
| name | type | label |
|---|---|---|
| outside_inside_outside | select_one underscores | outside_inside_outside |
On the choices sheet, you have:
| list name | name | label |
|---|---|---|
| underscores | AB_ZY_111_22_3333_444 |
AB_ZY_111_22_3333_444 |
| underscores | AB_ZY_555_66_7777_888 |
AB_ZY_555_66_7777_888 |
One source of confusion is that if you preview the form, which uses Enketo, you’ll not see any underscores removed from the choice labels. You will see that the question label has had its _inside_ portion changed to inside (italicized). It’s possible that the Enketo developers decided not to enable Markdown parsing for choice labels.
However, if you open the same form in KoboCollect, you’ll see that even the choice labels have had Markdown formatting applied:
Now—where you folks, @sieben and @zettberlin, are mistaken—the crucial part is that the VALUE (again, the name in the XLSForm choices sheet) NEVER has Markdown formatting applied. When I choose the second option and upload the submission, I can clearly see on KoboToolbox that the value is passed through INTACT AND UNTOUCHED by Markdown formatting, with all underscores present:
A note on civility…. I agree entirely with @wroos:
In fact, if he had not already made so much effort to help you (on a strictly volunteer basis!) and if I didn’t think this discussion would benefit others in the community, I simply would not have responded to such language.
