How to electronically sign a Jotform document

Hi - I was sent a link to a Jotform contract document. I cannot figure out how to add an electronic signature to the document. There is a box for a signature at the bottom of the document but I cannot access it with my mouse and am reading the document on my Mac but not on a touchscreen device - how do I electronically sign this ?

Thank you

Hi Rich,

Thanks for reaching out to Jotform Support. Can you take a screenshot of the document or send us the link so that we can see it better and assist you with signing it? This guide will show you how to do that.

Once we hear back from you, we'll be able to help you with this.

Hi Marehlene - Thank you for getting back to me about my electronic
signature query. I ended up pulling the Jotform document up on my iPhone
and from there was able to sign it with my finger.
For now, that takes care of what I needed.
Thanks for your help
Rich
