So, This is the four pages do: Index.php -> Test2.php -> Test3.php -> Result.php where Result.php displays the values of the textbox and radio buttons (if...else). But when I run the pages: Index.php go to Test2.php and just skip the Test3.php and direct go to Result.php. And in Reslt.php, I got this outcome: enter image description here
So, what should I do? I searched over the Internet and tried different solutions out there but couldn't work as I expected. After that, I discovered that there maybe has some problems with the button. So, again I go to Internet to find proper solution but failed to do so. Now I have no idea how to do that. Some explanations with code will be a big help for me. Thanks ;)
