Changing from 14 to 30 days Returns Period Via File Exchange

[jewelleryoflords2012]

I have tried a number of column headings but keep getting failure messages my last effort was the following:

Column 1: Action(SiteID=US|Country=US|Currency=USD|Version=585|CC=ISO-8859-1), Revise

Column 2: ItemID, (Enter ID Number Here 00000000000000000)

Column 3: ReturnsWithinOption, Days_30

Column 4: ReturnsDetails, Items must be returned within 30 days of receiving the item. All original packaging must be included.

Column 5: ReturnsAcceptedOption, ReturnsAccepted

However this fails with a strange message:

Status, Failure

ErrorCode, 10065

ErrorMessage, "Error - Currency is unchangeable when revising or relisting an item.|"

Strange message considering I am not trying to change a currency with any of my columns!

Any help would be appreciated.

Kind regards

Will
