Changes made to products of purchase order payment is not being displayed.

the problem is none of the changes really updated on the products for Purchase order payment.

I am adding products or changing price on existing product and preview is not showing me the changes. what is the reason for this. Let start resolving this issue first. How can I simply save this form. that is all I want.

thanks

I'm sorry for the trouble caused to you. 

I did check your form but do not see any difference between the prices of purchase order tool of form in editor and form in preview. I would suggest you to please let us know what changes you make in purchase order tool which is not being saved. 

I have gone ahead and cleared your form cache from here. I would suggest you to please try again and get back to us if the issue persists.

We will wait for your response.
