I am getting a NullPointerException on getconfigattrvalue. How do I trap for this?

I have a whole list of attributes that may or may not have been selected in config. I need to cycle through them to determine if they were selected what the contents is. So I need to trap for the possibility of the attribute not being selected. "NOT isNull" is not working.
