 * is this possible for 4 to 6 days
    `numdays>3 && numdays<6` so `if(numdays>3 &&
   numdays<6) { alert("you select a day between 4 to 6");}`

 * Find it
    for **4 to 6 days** `numdays>3&&numdays<=6`
 * so, for actions :
 *     ```
       if(nomjours<=3)
       	{
       		alert("you select a day between 1 to 3");
       	}
   
       	else if(nomjours>3&&nomjours<=6)
       		{
       			alert("you select a day between 4 to 6");
       		}	
   
       	else if(nomjours>6&&nomjours<=13)
       		{
       			alert("you select a day between 7 to 13");
       		}
   
       	else if(nomjours>13&&nomjours<=20)
       		{
       			alert("you select a day between 14 to 20");
       		}	
   
       else
       	{
       		alert("you select a day more then 20");
       	}
       ```
