'Other' from Select_Multiple

Question

One of the options in a select_multiple question is 'Other'.

Using ${Asset_Type}='Other' in the 'relevant' column works only for single choice. 
If the user select only the 'other' from the multiple choices list the 'other' field will open, but if the user will select more choices from the list, the 'other' field disappears.
How do I set it so the 'other' field will open each time the 'other' option is selected from the list, regardless if other choices are selected or not.
Thanks

Hi Ayelet,

It sounds like, given these issues, it might be better to not use the or_other keyword.  You can manually duplicate this by adding a value of 'Other' to your choice list and then adding the 'Asset_Type_other' question.  Relevancy can be controlled by the selected() function (see Formulas—Survey123 for ArcGIS | ArcGIS ); the expression would likely be something like 
selected(${Asset_Type}, 'other')

I'm not sure how to set the select_multiple [listname] or other.

The related table includes an 'Asset_Type_other' field.
When this field is included in the XLS form, when I try to publish the survey I get an error message that there are two survey elements named  'Asset_Type_other'.
When I removed this field to the form I got an error message that the field Asset_Type_other length is too short, regardless of  how long it is, (even if it is longer than the 'Asset_Type' field. )
And also, in this case, I can't change the length in the form because there is no such field in the form.

What am I missing here?
