I need a very simple problem fixing.
I have a html web form, i have a hidden field in that.
I need the data entered into 2 forms, combined together and created as the value of the hidden field before submission of form.
firstname + surname should equal the refid value.
I dont want it changing too much, because I am a beginner, and want to still understand it.
please see attached html file.
I removed form script action line to keep some detail hidden.
