How to edit the message "Total (before taxes, insurance, optional extras): "

[steveom]

I'm looking for some help with editing this message. I have tracked it down to the property_summary.html file where there is a line...
<!-- BEGIN: pricedisplay_calculated -->{PHP._MSG_TOTALBEFORE}<!-- END: pricedisplay_calculated -->:

Where will I find the place to edit this message.

Thanks
