Hi Takayuki,
Thank you for responding to this! The post you directed me to seems to be for forms where Ajax isn’t loading at all, but my form does seem to be working for the most part.
It is just that not all the error messages appear for all required field items, only some show up.
For example, if the nothing is entered into the form and I click send, only the popup for the quiz line shows up, plus the validation message that is linked to [respond]. Even though the other fields are required, no message shows up (ie for name, email, etc).
I don’t know if this is an issue with AJAX not loading properly or if I missed a step somewhere.
