var per_carton_quantity = context.newRecord.getSublistValue({
                    sublistId: "item",
                    fieldId: "custitem_case_qty",
                    line: q
                })
                log.debug('per carton qty', per_carton_quantity)

for some reason this is coming back blank even though -- there is data there. Any ideas. its a beforesubmit pulling the data fro the items in an IF

you have the wrong internal id

which internalid are you referring to? i am getting otehr fields without an issue in the same way

custitem_case_qty

is the internal id of an item field

I am not sure i follow. I am pulling a sublist from the transaction... it works for the next one

var length = (parseFloat(context.newRecord.getSublistValue({
                    sublistId: "item",
                    fieldId: "custitem34",
                    line: q
                })) || 0);

and what value are you getting for custitem34?

thnaks (sorry was dealing with someother stuff - just got around to this)
