Почему одна и таже книга excel с vba на одном компе работает а на другом нет? (и будет ли у вас работать эта программа:?

Dim oa, oc, ab, bc, cd, de, fi
Dim xa, ya, xb, yb, xc, yc, xd, yd, xe, ye

Sub koords()
'A
xa = oa * Cos(fi): ya = oa * Sin(fi)
'S
xca = xc - xa: yca = yc - ya
ac = Sqr(xca ^ 2 + yca ^ 2)
ca = (ab ^ 2 + ac ^ 2 - bc ^ 2) / (2 * ab * ac)
sa = -Sqr(1 - ca ^ 2)
xb = xa + (xca * ca - yca * sa) * ab / ac
yb = ya + (xca * sa + yca * ca) * ab / ac
'D
xbc = xb - xc: ybc = yb - yc
xd = xc + ybc * cd / bc
yd = yc - xbc * cd / bc
'E
xe = 0
ye = yd + Sqr(de ^ 2 - (xe - xd) ^ 2)

End Sub
