I was trying to implement the V-Lookup routine posted here:
http://en.smath.info/forum/yaf_postst673_lookup.aspx

However I receive the error "Nominal - not defined".

My questions are as follows:

1. Is there a location where I can find more information on the error messages.
2. What am I doing wrong in the attached page to recieve this message?
3. Is there a way to correct this?

Thanks and sorry if this is basic...I am a new user.

the first row of BPT consists of tags and not by variables
labels are shaking and should be placed in quotation marks
for example "Nominal"
