You could do a check on the value something like

if (tBox.value != ""){//proceed to next question}else{alert("Please enter a value in the textbox")}
if (tBox.value != ""){//proceed to next question}else{alert("Please enter a value in the textbox")}

try something like this:

 JavaScript / DHTML / AJAX Syntax (Toggle Plain Text) 
function check_form()
{
if (document.getElementById('the_other_checkbox_id').checked==true)
     if(document.getElementById('the_textbox_id').value=="")
          alert('something');
    else
          go_to_next_question();
}
function check_form()
{
if (document.getElementById('the_other_checkbox_id').checked==true)
     if(document.getElementById('the_textbox_id').value=="")
          alert('something');
    else
          go_to_next_question();
}
