Ok, I'll ask the question here since support has literally taken 3 weeks to get back to us. When I asked for a status update they started asking for information we had previously submitted to them again as if they had never seen the issue. Meanwhile they could simply look at all the information they asked for in the same chain of emails. 

If anyone that actually has some useful knowledge of this can help since Zoho Support isn't, that would be great.  

We have built a webform in CRM that we use in a Zoho Landing Page which is still in beta. Despite it being using in Zoho Landing Pages this form should work anywhere, but doesn't. 

Our CRM webform, which was built for the Leads module. It contains a hidden field of "Lead Source" with a default value of "Landing Page", so we can track new leads that we obtained their information from the landing page. Seems pretty simple right out the box right??? Wrong!

When a user submits the form, every field records correctly but it always leaves the Lead Source null. Currently the only way we know that it was submitted by the form is by using a "Landing Page" tag which causes us to look in two different locations for the various values of how we obtained the lead. Not really an acceptable way since this also causes us to have to build two different workflows in our Zoho Campaigns for the same thing. 

Per Zoho support we have refreshed the form in the Landing Page multiple times with the same results. I  wish Zoho would quit having this be their standard reply because it isn't helping.  We have confirmed the fields are correct in our webform multiple times also.

It seems I spend more time with Zoho support trying to debug their products more than I debug our own platform. I'm really starting to feel I made a mistake integrating our SaaS with Zoho.
