nlapiGetLineItemValue('item', 'itemid', x)...

We are a software company, and we sell support minutes for our software.  One thing we'd like to do is update the customer record with more support minutes when they purchase those minutes.  So I have added a field on the item record that designates how many minutes should be added by purchasing that item.

My plan was to execute the following lines of script 'afterSubmit' when a sales order is created...

var numberOfLines = nlapiGetLineItemCount('item');
 
for( var x = 1; numberOfLines >= x; x++)
{
  var itemName = nlapiGetLineItemValue('item', 'itemid', x);
  var itemRecord = nlapiLoadRecord('item', itemName);
  var supportMinutes = itemRecord.getFieldValue('custitem_minutes);
