Why are some fields not showing up when I embed my form using the source code?

I embedded the source code and the problem is still present.  The fields are hidden.  

I'll wait to hear from you and see if you are experiencing the same thing.

I have checked your code and I can see the same you are reporting; however, the fields currently have the hidden property due to the conditions you have set up: 

This seems to happen due to the conditions you have set up on your form, seems like this is generating the conflict: 

I would recommend you to change your conditions, here is  a screenshot with the changes marked: 

I hope this helps. 

I changed the conditions as you suggested.  But now even when I embed the link, the conditions are not working at all.

I have already cleared your forms cache and seems like the conditions are working now, here is what I could see after a few tests: 

Would you mind to try again please? 

Please let us know how it goes. 

OK.  It works on my website when I embed the link.

But the original problem of the fields missing when I embed the source code is still there.

I can see the issue persists on your webpage, although I have tested the exact same source code on my end and it worked. 

I can see you are using jQuery on your webpage, may be that there is any kind of conflict with the code in the form, may you please try adding the noConflict() code to your page? 

You will find info about the function on this link: https://api.jquery.com/jquery.noconflict/ 

I hope this helps. 

I'm using Wordpress and am not familiar with the noConflict code.  Where do I put it and what is the exact line of code to enter?

That depends on your code but you should put it between the script tags, like in this example:

But again, it depends on the current code you have. More information you can find here: https://www.w3schools.com/jquery/jquery_noconflict.asp
