Get Calculated Field from Table A -> Table B

I have been creating a personal financial statement that does the math on the balance sheet and income statement.

I also have a few table of schedules in the form. On the footer of those tables I total up what is typed into each one of those schedules.

What I want to do, is get a calculated value from another table and fill it on a table above it. Something along the lines of

BalanceSheet.Row[1].CASHINBANK = ScheduleATable.Row[4].TOTALBALANCE;

I am really not sure how to do this, I tried various ways to accomplish it.
