Random int generator + if / else if / else ) 1 through 5 . .. always returning false .. why??

<button onclick="func()">push</button> <p id="in"></p> <p id="out"></p> <script> var x = document.getElementById("in") x.innerHTML = Math.floor((Math.random() *5) + 1 ); if ( x < 3 ) { document.getElementById("out").innerHTML = "too low"; } else.if ( x == ) { document.getElementById("out").innerHTML = "bingo"; } else { document.getElementById("out").innerHTML = " too high" } </script> </body> </html> no matter the number. the contents of id="out" is always displaying "too high" ... aka FALSE

First of all, you have a syntax error at the else if statement. Then, it says func is not defined. You need to include everything under that function
