Thanks, that solved it. It's very odd because the wizard appears to write it correctly the first time, but when ou go back into the behaviour to amend anything (i.e change USD to GBP), it then forces you to fill in a couple of other fields and then obviously writes this extra code in.
i guess you wouldnt come across it unless you had to do what i had to do in the first place, i.e. go the US route and then convert.
anyway, thanks again for your prompt assistance. i can cope with strange anomalies as long as they get sorted quickly!
cheers eric
