Glad it worked for you. Sometimes, my years as a college Computer Science Professor comes out without me realizing it.
You do not need the
<p> </p> tags. They do no harm, but they serve no purpose, at least in this context. Also, the apostrophy (*) makes the field required, so adding (required) doesn't, in and of itself, do anything. If someone fills out the form without entering something in a required field, they will get an error message next to each field that is empty and the form will not be submitted.
'[checkbox] line, I would suggest that you shorten "Iaminterestedinlearningmoreabout" to something like "interest". They are merely the name of the field. You could just as easily use "field1", "field2", etc., except that "interest" is much more meaningful.
