Wpforms – No success so far :-(

Hi there,

thank you very much for your work!

I’ve been trying but without success to pass the lead source in WPFORM…

I filled the class field like on your screen shot but the field is then empty after the submission>>> https://ibb.co/HpKF5b6

Is there anything to add in the field value itself >> https://ibb.co/41tV2NS

If I embed on the page the short code I can see the source (and I see it too in google analytics live).

Am I missing something?

Thank you very much in advance for your help!
