the name in the black box around the field says start mileage, end mileage and total so is that not the field name? I have tryed using the simplfied field notation as start mileage-end mileage and start mileage - end mileage but neather one will work as written, I have looked at taht post but can't find the correct answer,

Simplified field notation does not directly support spaces in field names. JavaScript allows special characters like "." and " " when the special escape character, "\", precedes the special character. So you could use:
end\ mileage - start\ mileage
in the simplified field notation field.
You can use the custom calculation script but then you need to use JavaScript notation to obtain the field object and value property and use the appropriate operator. The custom JavaScript calculation could be:
event.value = this.getField('end mileage').value - this.getField('start mileage').value;
end\ mileage - start\ mileage
in the simplified field notation field.
