Hello @jitendrak 

 

You will have to create a javascript function to do this. 

 

Here is an example

<script>
function updateCtxValues(){
  var purchaseNumber=document.getElemebtById('purchase_number').value;
  document.controller.setValue('/ctx/vars/my_purchase_number', purchaseNumber);
}
</script>

You will have to call this function on the form submission by onclick event

<input type="button" onclick="updateCtxValues()" value="submit">

Also, make sure your purchase number input has an id attribute of value "purchase_number"

 

Let me know if that works.

Thanks
