Tax is suddenly removed when the submit button is pressed

Hello,

So the total on the form includes tax (GST).

But now when the submit order is pressed, it suddenly deletes the GST?? And the total does not include the gst tax...

Any idea's that may solve this? Thanks so much!!

The problem happens since you're performing calculations on the widget and affecting the value with some conditions, I would recommend you to either delete the formula you currently have or remove the associated conditions, this way the conflict does not happen. 

Here's my cloned form where I did the change and it worked: https://form.jotform.com/80156670997974 

I hope this helps.
