On the first one....at least in the Personal editions, the $0 in the interview usually indicates that there is a Supporting Details (SD) sheet attached to that field.
Usually, a double-click on the field will pop that SD sheet up, and you can make entries on that SD worksheet, or delete the SD entirely and leave the field open for direct entry.
A second way if double-click doesn't work is to click on the field once, then go up to <Edit> and select <Add Supporting Details from the dropdown...then either use the SD sheet, or delete it to release the use of the main interview entry.
