Answer 2

Assuming the text in your scrolling field is formatted consistently as in your example:

5 USA
5 UK
4 EUR
etc.

You can do something like this:

put fld "myScrollingFld" into tList
put 0 into tTotal
repeat for each line tLineContents in tList
   put word 1 of tList into tNum
   if tNum is a number then add tNum to tTotal
end if

Answer 3

on mouseUp
  repeat for each word thisWord in fld "Myfield"
      if thisWord  is a number then add thisWord  to tSum
   end repeat
  answer tSum
end mouseUp
