I'm working on a

validateLine

client script and I'm getting a "TypeError field.getSublistName" error when I try to

record.setCurrentSublistValue

. I have the line selected and if I do a

record.getCurrentSublistValue

it gives back what is currently there. This is on a Vendor bill and I have done a

record.load

to get into the Purchase Order and while that is loaded I have also loaded the Item Receipt which is where I'm trying to set a value and get the error.
