convert existing field

Hi there all,

I have added a custom filed "%release type%" to my all collection.
Now i want to convert the field into "%release%" without deleting the info..

Thanks in advanced

In a way you have to delete the information - after you have saved it:

Create an action group with 2 actions:
Format value for release
Format string:%release type%
Delete field: release type

you are very kind sir
thank you very much
