Subject:      Strange Error, please help

The following error is very confusing to me, any hints. I've checked and
checked, but I don't see a spelling error. Am I just blind or what? I
sort the data by this makeuni variable and the I want to output the first
observation of each. Am I just clueless, dumb, or is my SAS acting up.
If there is bonehead mistake, please feel free to mock me.
 
Thanks in Advance,
 
Rob
