I have an embedded (Iframe) Zoho Creator form on my external website which I am trying to pre-populate via a URL query string.

The query is populated from merge tags, meaning the value changes depending on who clicks the link.

I'm having trouble getting the web page to pass on the parameters to the embedded Iframe....

Example as a link from an email (where the name values would change given the merge tags:

<mywebsite>/edm-enquiry/?fname=Emily&lname=Smith

Iframe embedded into my website:

<iframe height='500px' width='50%' frameborder='0' allowTransparency='true' scrolling='auto' src='https://creator.zohopublic.com/<user>/<app>/form-embed/Learn_More/uR1k1rZCfB0F6j61MnSsSzd2dRKZHn5Q5MaJjpeY73eCYuJbDC3qk3Zr4SavH09xAOtpbFtVY5x3M6zDDWEx3H4yw9YVdXTgmOgM'></iframe>

Any ideas how I can pass the parameters to the embedded form?

Thanks!
