Use one web component and one global variable

When screen init,
Set web1 url to (in the above sheet url just change the edit text into export?format=CSV&range=C2)
Call web1.get
Call notifier1 to spinning notification

When web1. Got text
Set global variable to get response content
Dismiss notifier1 spinnin notifier

Then use that variable into that missing place

Here change the texbox to variable
