How to stop scrolling of zoho sheet embedded in a website

I am using zoho sheet as a calculator. I embedded the following html snippet in this website.

<iframe width="500" height="400" frameborder="0" scrolling="no" src="https://sheet.zoho.com/publish/rfcircuits.info/pi-match-lp2"> </iframe>

The width and height of iframe are adjusted to exactly match the dimensions of the sheet. But even with scrolling="no" option, the sheet is scrolling after embeding in the webpage. Is there a way to avoid scrolling of the sheet inside the web page or atleast hiding the scroll bar?

Thanks....
