I need to use spaces and other not recommended characters in the 'name' & 'label' field because I can't have my 'name' (when they are less than attractive) items be displayed in the instance_name (which should actually be instance_label). Basically my name and labels need to be identical for the instance_name to display with some pleasantry. Otherwise name of b1 and label of Beat 1 leaves me with a instance_name of "Beat: b1" when it needs to read "Beat: Beat 1".
What are the potential issues that may arise when using spaces and other unrecommended characters? it is only a warning... and I can use spaces in coded value domains so I am not sure the issue.
Also, is there less chance of issue if I choose NOT to 'Create coded value domains from choices'?
