To track the lead sce data on all your Jotfrom forms, simply add the following html code at the beginning of your Jotform embed code (iframe):
data-leadsources-iframe
So if your iframe looks like this:
<iframe
id="JotFormIFrame-123456789"...
Edit it like that:
<iframe data-leadsources-iframe
id="JotFormIFrame-123456789"...
