13 formulas:
split({periodbalance}, ';')[1]
for January on through [12] for December (if that's how they're split).
Last formula to add the 12 fields and the opening balance. That's how I would do it, may be an easier way, may not. Give it a shot.
EDIT:
I haven't tried this but you may be able to just make one formula:
split({periodbalance}, ';')[1]
+
split({periodbalance}, ';')[2]
+......
+
{openingbalance}
I've never tried it but would be interrested to see if it works.
