I am receiving a division by zero error in relation to the following:-

(Sum ({@Payments},{aps_group.code})/Sum ({@Invoice},{aps_group.code}))*100

It is strange, as the report was written some time ago and this error has only just appeared.

I am not particulary au fait with Crystal Reports, so a laymans response would be appreciated.

I am using Crystal Reports XI if that helps.

Thank you in advance.
