Selecting blank values in a prompt from dynamic list

[gianfranco]

Hi,

I have a prompt where the user selects values from a dynamic list. The column is a character.

One of the possible values of this column is a blank, but when the user selects the blank, SAS interprets it as if the user had made no choice instead of interpreting as choosing the value "blank".

--> How can a user choose a blank value from a prompt coming from a dynamic list?

Thanks in advance!

I suspect you are going to have to share how you are attempting to use this "blank" value, as in the code actually using it.

And describe what is supposed to happen when the "blank" is selected.
