Could someone please tell me what might be wrong.  When I display the grand total I get lots of zero's that I don't want.  

//global
double _totalBalance              = 0.0;

//method scope
double paymentAmount           = 0.00;
double pendingPaymentTotal       = 0.00;

//retrieve from db
paymentAmount = rs.getDouble("Amount_Paid");
pendingPaymentTotal += paymentAmount;

//get the total balance
_totalBalance += pendingPaymentTotal;

//This shows the correct balance
These are the two balances that make up the one below that is message up:
Ex. 25196.67
Ex. 30627.23
sb.append("<td><b>" + String.valueOf(pendingPaymentTotal) + "</b></td>");

//This show lots of zero's that should not be visible.
Ex. 55823.899999999994
agScriptHelper.alert(String.valueOf(_totalBalance));

You need to use DecimalFormat to control the number of decimal places displayed:

DecimalFormat fmt = new DecimalFormat("#.##");
agScriptHelper.alert(fmt.format(_totalBalance));
