hello guys! can anyone help me for sum or substration of two tabular section located in differents documents.

Hello Ndayisenga,

would you describe your task in more detail?

i wanna substract loanAmount in document called loan with RepaidAmount in document called RepaidCredits

Remaining = loanAmount - RepaidAmount

Hi Ndayisenga,

see this example pls:

sumRepaidAmount = docRepayingCredits.RepayingBook.Total("RepaidAmount");
sumLoanAmount    = docLoans.YourCredits.Total("loanAmount");

Remaining = sumLoanAmount - sumRepaidAmount;
