I'm trying to format my SharePoint form to show/hide a column based on a selection from another column. If 'Other' is chosen from a column named 'Communication support', I'd like a free text column 'Other (please specify)' to appear.
I tried this simple Microsoft guidance (https://docs.microsoft.com/en-us/sharepoint/dev/declarative-customization/list-form-conditional-show-hide) to produce this:
=if([$Communication support] == 'Other', 'true', 'false')
As a result my 'Other (please specify)' column disappears but doesn't appear when 'Other' is selected under Communication support.
This might be a very simple questions for you, I'm only a beginner in SharePoint formatting.
Many thanks for your advice!
