Hello Gerard,
When you are previewing the specification, are you still in the Designer or are you in Adagio Invoices?
Please exit from Adagio Invoices and then go back into the Designer and edit the specification. If the unit fields appear to be formatted correctly, please go to File, Preview and check the alignment specification.
If the fields are not formatted correctly, remove them from the specification and reinsert them now that your Options, Properties settings have been changed. Be careful to remove all unit fields. You may have them in more than one section or you may have one stacked on top of another.
If the fields are formatted correctly on the alignment specification, go to File, Specification Options and make sure that this specification has a unique name.
Now go back into Adagio Invoices and try to preview a sample invoice.
