Answer 3

The buttons disappear because the `document.write(...)` call in the JS section is rewriting the document content.
Your "Press" button and the text input has the same ID, you need to assign different ID for those elements.
Get a reference to the text input element, and update its 'value' property accordingly ...
if(RandomNmbr < 0.5)
{
document.getElementById("head").value = "head";
}
else
{
document.getElementById("head").value = "tail";
}

Answer 4

Line 12 and 16;
document.getElementById ('inpt').value = ...;

Answer 5
