Hi GS,
DollarText is, naturally limited to currencies that use dollars (not just USD). You could, however, use a field with a CardText switch on the integer portion of a value to extract, say 'Pounds' and then multiply the decomal part by 100 and use another field with a Cardtext switch to express the 'Pence' in words. For example, see what happens with a field coded as:
{QUOTE{ASK Value}"{=INT(Value) \* CardText} pounds and {=MOD(Value,1)*100 \* CardText} pence."}
Note: all the field braces (ie '{}') must be created in pairs via Ctrl-F9.
Cheers
