Report Designer - Sage 200 online - Conditional printing not working

I have got a text box setup on the footer of the  SOP invoice layout.

if I set single condition - say  print if the Account currency is USD  other wise suppress print  - then this works

If however I set multiple conditions - print id Currency is USD or GBP then it does not work. 

The work around seems to be to create a duplicate text box  for each currency which I prefer not to do.

I am using the "Wizard" dialog screen to set the conditional info.

the report designer is V4.0 

Any Ideas please?
