Let me explain...
it is an IF statement
the true result being ../../../my:OpeningBal
the false result being preceding-sibling::*[1]/ClosingTransBalance
i.e. it sets the value to the field ClosingTransBalance of the previous item in the Repeating table.
Condition: count(preceding-sibling::*/TransID) = 1
it counts whether there is ONE item in the items repeating table
Using preceding-sibling
Linear Mode
