Hi @cdalessandro. Thanks for your quick response!! It does not make any difference in the result so  I´ll try to find other options. All suggestions/ideas are welcome :)

            Hi @warrengis! I have modified the python according to my real attribute names and I get the error "Python Exception <SyntaxError>: can't assign to operator (<string>, line 8)" 
I have no idea why that happens. My script looks like this  and it is done following the same steps than in yours. Why does not  it work?
I have to say that I have no idea how to use python so...
I hope somebody can help me.
Thanks!!!

 
 
                
     
                                    
            This should let you select which attributes you want to remove blanks from
delete values python.fmw

	 Hi @ebygomm, I sent you a dm, but in case you didn’t see it, and see this first, could you please repost your delete values python.fmw I can’t seem to download it.
(Or, if someone else sees this and has it could they please share it.)
Many thanks
