A common support request we get is from users who have a select_multiple field that has "other" as one of the answer options and, after this multiple choice question, the user has a text field that is meant to appear to "specify other" if "other" is selected as an answer option.
However, the relevance for the text field does not appear to work properly: if "other" is the only answer selected, it appears as expected. But if additional answer options are selected along with "other", the text field is skipped.
Lets say the multiple choice question is named ${multchoicefield} and the internal value for the "other" answer option is 99.
The problem
This happens because the relevance expression for the text field is coded as:
${multchoicefield} = 99
While such an expression will work fine if the multiple choice question was a select_one question, it will not work well when you have a select_multiple question that could have 99 ("other") and additional answer values selected at the same time.
