I have simple spreadsheet for converting UK £s to Euro it is set up to put
the current rate into a box and it converts automatically from one to the
other from 50p to £100. I have sent this to a couple of people but they have
`excel viewer` rather than `office` so the programme doesnt work for them.
Is there a way around this, is there something I could download and redo so
it works for them in `excel viewer`?

thanks
