I can pick up the data.
var bocaCheck = root.selectSingleNode("my:boca").text;
batch.selectSingleNode("/Batch/Method/Field[@Name='Boca']").text = bocaCheck;
with updated CAML
<Field Name="Boca" />
created the column "Boca" in the SharePoint list
My issue is that for some reason when I submit the data it populates another column in SharePoint called "Printing Area." Anyone know why this might be the case?
