inline functions - How do I rename a sharePoint file to include a date using Nintex -

i'm trying use 2 workflows archive files when created or updated. first moves copy separate doc library. no issues second should rename file once arrives append date (and possible timestamp) end of file unique record.

i trying set variable called archive_name , setting field value archive_name before commiting change.

i using fomula set variable

name-fn-formatdate(current date,yyyy-mm-dd)

both name , current date recognised variable.

when run name stays same , not append date. if run as

fn-formatdate(current date,yyyy-mm-dd)

the name changes desired date proving formula working, text being assigned archive_date variable , variable being applied field value.

what doing wrong?

i believe need concatenate 2 variables. & operator can used in place of concatenate function. thus; name&fn-formatdate(current date,yyyy-mm-dd)

hope helps
