can somebody say me how do i make multiple conditions at once in javascript?
The code that i include shows you how i do it now, but i would like to know how to make it one 'if(...)....{}'
not 'if(...){ if(...){...} }'
if (!document.form1.parents.checked == 1)
   {    if (document.form1.gebjaar.value > "1990") {
      		alert("You have to accept the parents approval checkbox to go on");
      		return false;}

I have not used java in quite a while but I remember using the and (&&) operator for the same thing you are trying to do or use the or (||) operator

Or you may use shortened way like the code below basicly its logic is
 condition ? run if condition is true : run if condition is false
!document.form1.parents.checked == 1 ? alert("You have to accept the parents approval checkbox to go on") : document.form1.gebjaar.value > "1990" ? alert("You have to accept the parents approval checkbox to go on") : return false ;
