I am working on a DOE that has string values for levels. I was able to find how to input the string values, but I have been unable to figure out how to enter levels with spaces. It appears that the space is used as the delimiter between the levels. I've tried quotes and a few other characters to indicate that two words go together--I've been unable to find if this is possible and/or the characters to use to represent this. Has anyone discovered how to do this?
