From the link you gave me: "Next enter the following string into the 'Find what' box: (=952 ..)(\$h)([A-Za-z0-9.]*)(\$i)([A-Za-z0-9.]*)(\$.*\$b[A-Za-z0-9.]*)

This will take the data from the $h field (and the data could be capital letters, lower case letters, numbers and decimals) and the data from the $i string (and the data could be capital letters, lower case letters, numbers and decimals) and $b is the last subfield in the 952 field. TIP: This regular expression may need to be changed depending on the type of data you have in your system. Libraries that use the LC classification system in particular may need to tweak the “replace” command to find and move cutters. And enter the following string into the 'Replace with' box: $1$o$3 $5$6 This string is saying stay in the same field number as in parenthesis #1, move the data from parenthesis #3 of the 'Find what' string next to $o, add a space, take the data from parenthesis #5 and move it to $o as well, then check to the end of the field and leave all the other subfield data alone." ----------------------------------------------------------------------------------------------------------------------------------------------------------------- I tried doing the above on my records, but I think it only finds the data and doesn't replace anything, because it said "0 modifications were made." and took a few seconds to finish. Any ideas on how to move the subfields? regards, Maxwell
