SET a.IDGRP = b.IDGRP
      
,a.[TEXTSTRE1] = b.[TEXTSTRE1]
      
,a.[TEXTSTRE2] = b.[TEXTSTRE2]
      
,a.[TEXTSTRE3] = b.[TEXTSTRE3]

I looked at this site before (and a few others) and one it is talking about my alias being out of scope between the sub query and the outer query; adn two my query is a simple update query. I even tryed just updating the one field and it still gave me this error. Unfortuantly, I do not see how this would apply here, I was not able to make the connection. if you see, based on this, what I am doing wrong prease let me know.
Thank you
