Find and Replace RegEx problem in Studio 2017 SR1

Question

Hi, 
 I would like to change the order of words in several segments from "word1 word2 word3" to "word3 word2 word1". The Find and Replace regex expressions look like this: 
 
 "Find what is OK" but for "Replace with" Studio throws the error message 'The replace regular expression has an error and cannot be used. Reference to unde fined group number ..." 
 Is there any solution? 
 Thanks in advance 
 
 Sandor

You need to use $ instead of \ 
So you put $1$2$3 in the replace field.
