Using Index with nested small, not updating when I insert row of data on the reference page

[dpnyc]

Hi, I have this code that looks to my sheet with Cash Flow Transactions, and returns values associated with the date range (O7 = beginning date), if not it returns the period end date (P3). When I insert a row in my Cash Flow Transactions Page the formula does not update for the new row (instead it skips a row). Does anyone have any ideas on how I can fix it? The problem part of the function is:ROW('Cash Flow Transactions'!A1)),COLUMN(('Cash Flow Transactions'!A1))) which is what is skipping when I insert, and returning a ref# if I delete.

=IFERROR(INDEX('Cash Flow Transactions'!$A$4:$A$313,SMALL(IF(($O$7<='Cash Flow Transactions'!$A$4:$A$313)*($P$3>='Cash Flow Transactions'!$A$4:$A$313),MATCH(ROW('Cash Flow Transactions'!$A$4:$A$313),ROW('Cash Flow Transactions'!$A$4:$A$313))),ROW('Cash Flow Transactions'!A1)),COLUMN(('Cash Flow Transactions'!A1))),$P$3)

Thanks!
