Query in Nintex Form insert reference not working

[JuanHooi]

I have create a query to get the data from sql to the sharepoint, when i test the query it will no have problem but when i go back to sharepoint the data won't pop up. I figure is that the reference problem or sharepoint problem or my reference put wrongly

Hi,

If you hard code a Purchase ordr number does it work?

Are you getting this number from a named control?  If so what sort of control type is it?
