Sorry about that the reference and code is working except when save as for new document. This different but i think the code is the same. Im trying to use in my other form the Filename for that is
KR-A359-STR-00001-SHT 01 OF 01-00 and i need to extract that filename into four groups.
1. STR-00001-SHT 01 OF 01-00
2. KR-A359-STR-
3. SHT 01 OF 01
4. 00

and the code i used is the one i post but there is a problem whenever i save as for a new document and change the filename it will not reflect automatically in the new document.

Thank you for your reply.
