I believe the issue is here: (notice only the / is red) <field name="PRIORITY_DATE" alias="PRIORITY_DATE" visible="true"/>
<format precision="0" usethousandsseparator="false"/>
</field>
Should be: <field name="PRIORITY_DATE" alias="PRIORITY_DATE" visible="true">
<format precision="0" usethousandsseparator="false"/>
</field>
Notice I removed the / from the end of the <field> tag (after visible="true"). Putting that slash there tells it that the <field> tag is closed, so it can't assign the "child" format tag to it.removing that / keeps it open, then it will assign the format to that field tag, then you close the field with </field> I tried removing </field> and that removed the popup error HOWEVER the original problem still remains - I still have commas in my number: 19,990,131
Since you are closing the field tag on the original line, the format was being seen as it's own element (not a child), then the </field> tag was no longer associated with an open field tag as it was already closed on the original line. Thus the error, trying to close something that isn't "open".Notice there is not </field> for the items that don't require formatting (or other child tags) as the / at the end closes it.Hope this clarifies it for you,R_
