Purchase order sample - drop down list populating another drop down list

Question

hello, when i use this sample script, it works fine. but when i add additional arrays to it, it doesn't work at all. please let me know what i need to change in this script in order to add additional items into the drop down lists. here is the script that works (displays 3 options in first drop down list (blank, option, another option)):
// This script object controls the interaction between the carrier and plan Drop-down lists.
// The array contains the carriers and the corresponding plans.
var myCarriers = new Array(new Array(2), new Array(14), new Array(17)); // Create a two-dimensional array.
// For each carrier, add a 'new Array(number of plan +1)'.
// Define the carrier and the corresponding plans.
// The array syntax is arrayName[index][index].
// The first index number represents the carrier,
// the second index number is the actual data value.
myCarriers[0][0] = " "; // The first items in the Drop-dowm Lists should be blank.
myCarriers[0][1] = " ";
myCarriers[1][0] = "ANERT"; // The first data value is the carrier name,
myCarriers[1][1] = "MC250"; // the rest are plans.
myCarriers[1][2] = "MC2501";
myCarriers[1][3] = "MC5002";
myCarriers[1][4] = "MC5003";
myCarriers[1][5] = "MC1000";
myCarriers[1][6] = "MC2000";
myCarriers[1][7] = "MCHC2300";
myCarriers[1][8] = "MCHC3000";
myCarriers[1][9] = "MC2500";
myCarriers[1][10] = "MB";
myCarriers[1][11] = "P500";
myCarriers[1][12] = "MHH3000";
myCarriers[1][13] = "MHH5000";
myCarriers[2][0] = "BCCA"; // This is a new carrier, see how the first number is now [1].
myCarriers[2][1] = "S Plan";
myCarriers[2][2] = "BPlan";
myCarriers[2][3] = "P40";
myCarriers[2][4] = "P30";
myCarriers[2][5] = "P35*";
myCarriers[2][6] = "P45*";
myCarriers[2][7] = "Ad25*";
myCarriers[2][8] = "Pr20";
myCarriers[2][9] = "Pr10";
myCarriers[2][10] = "PH750*";
myCarriers[2][11] = "PH500*";
myCarriers[2][12] = "2400HD";
myCarriers[2][13] = "3500HD";
myCarriers[2][14] = "2000HD";
myCarriers[2][15] = "LH1500";
myCarriers[2][16] = "LH3000";
// This function will populate the carrier Drop-down List.
// This function is called from the initialize event of the carrier Drop-down List.
function getCarriers(dropdownField)
dropdownField.clearItems();
for (var i=0; i < myCarriers.length; i++)
dropdownField.addItem(myCarriers[i][0]);
// This function will populate the plans Drop-down List for any event EXCEPT the change event.
// This function is called by the initialize event of the plan Drop-down List.
function getPlans(carrierField, dropdownField)
dropdownField.clearItems(); // Clear the items of the Drop-down List.
for (var i=0; i < myCarriers.length; i++) // Look through all the carriers until we find the one that matches the carrier selected.
if(myCarriers[i][0] == carrierField.rawValue) // Check to see if they match.
for (var j=1; j < myCarriers[i].length; j++) // When they match, add the plans to the Drop-down List.
dropdownField.addItem(myCarriers[i][j]);
dropdownField.rawValue = myCarriers[i][1]; // Display the first item in the list.
// This function will populate the plans Drop-down List for the change event.
// This function is called by the change event of the carrier Drop-down List.
// The first parameter is simply a pointer to the xfa object model.
function getPlansOther(myXfa, dropdownField)
dropdownField.clearItems(); // Clear the items of the Drop-down list.
for (var i=0; i < myCarriers.length; i++) // Look through all the carriers until we find the one that matches the carrier selected.
if(myCarriers[i][0] == myXfa.event.newText) // Check to see if they match. Note: we have to use the event.newText in this case because

change hasn't been committed yet.
for (var j=1; j < myCarriers[i].length; j++) // When they match, add the states/provinces to the Drop-down List.
dropdownField.addItem(myCarriers[i][j]);
dropdownField.rawValue = myCarriers[i][1]; // Display the first item in the list.
when i try to add 4 more arrays (add items to first drop down list and second drop down list), nothing displays in either drop down lists. please let me know the items that need to be changed - besides these items (i know i need to add arrays and add myCarriers[1][0],[2][0],[3][0] to [6][0] --- for 4 additional items in the first drop down):
var myCarriers = new Array(new Array(2), new Array(14), new Array(17)); // Create a two-dimensional array.
// For each carrier, add a 'new Array(number of plan +1)'.
// Define the carrier and the corresponding plans.
// The array syntax is arrayName[index][index].
// The first index number represents the carrier,
// the second index number is the actual data value.
myCarriers[0][0] = " "; // The first items in the Drop-dowm Lists should be blank.
myCarriers[0][1] = " ";
myCarriers[1][0] = "ANERT"; // The first data value is the carrier name,
myCarriers[1][1] = "MC250"; // the rest are plans.
myCarriers[1][2] = "MC2501";
myCarriers[1][3] = "MC5002";
any help would be greatly appreciated. thank you!
