hi,
that is because excel is programable using the computer language visual basic.
as far as inserting a "flash file", unless it is in vb and designed for
spreadsheets, i doubt it would work. but in excel, press alt+F11. this will
bring up the vb editor. here you can write, paste or import code.
regards.
FSt1
