In which cases does your referral widget not send a referral link?

I got the completed form, but it didn't have a referral link. The previous completed form had the link. I tested the form and got the referral link.

It should always send the referral link? If it is failing, you could also try using the Get Form Page URL widget: https://widgets.jotform.com/widget/get_form_page_url 

I used "get form page url". But I get link like this - http://www-interierus-ru.usrfiles.com/html/f77359_473460036e42dc8cf1af9a6d774c2733.html

Not website/price or another page.

I have checked the link you have provided on your other posts and I can see the form has been embedded here: http://www.interierus.ru/price?utm_campaign=test_campaign&utm_content=test_content&utm_medium=test_medium&utm_source=test_source 

However, seems like your form is loaded within an iFrame, and the form's original link is this one: http://www-interierus-ru.usrfiles.com/html/f77359_473460036e42dc8cf1af9a6d774c2733.html 

This is why you can see that link showing as "Get Form Page URL" value and the correct link "http://www.interierus.ru/price?utm_campaign=test_campaign&utm_content=test_content&utm_medium=test_medium&utm_source=test_source " showing up as referral. 

I would suggest you to re-embed your form directly on your main page "http://www.interierus.ru/price" so you have the correct value, here is a guide where you will find our embed methods: https://www.jotform.com/help/67-Which-Form-Embed-Code-Should-I-Use 

I hope this helps.
