Sorry for the delayed response.
It seems you had sorted out the issue. When I checked your form http://www.jotform.us/form/42423604789157 I can now see the Purchase Order field is working on the form.
But just to be clear on how to delete the tool, you can click on the red X icon when the field is selected to delete the field/tool.
Inform us if there is more we can assist you with.
