Hi Kingswood,

I'm not sure to what extent you can't change things. If you can't change anything, then you can't insert the necessary field coding to generate the required output.

Assuming, though, you're allowed at least that latitude, then you can simulate a ticked/unticked checkbox via field coding like:
{SYMBOL {IF{MERGEFIELD CheckBox \* Upper}= "X" 254 168} \a \f Wingdings}
or a a checked/checked checkbox via field coding like:
{SYMBOL {IF{MERGEFIELD CheckBox \* Upper}= "X" 253 168} \a \f Wingdings}
where 'Checkbox' is the name of your data field and it contains 'x' or 'X' to indicate the ticked/checked state.

You can't actually populate a checkbox formfield, though (assuming that's what you already have).
