Odd summation, else, even summation, script help
Here are the instructions from my instructor:

• Define a function getSum5(arg_n, arg_opt), that if arg_opt is equal to 1, it calculates the sum of odd numbers from 1 to arg_n: 1+3+5…+arg_n; if arg_opt is equal to 2, it calculates the sum of even numbers from 1 to arg_n: 2+4+6+… +arg_n.
• Example:
Input: n=6, opt=2
Output: 12

Here is my botched code
Code:

``` <html>         <body>         <script type="text/javascript">                 var input1=Number(prompt("Enter an integer:"));                 document.write("The total even or odd summation value is: ", getsum5(input1));                 function getsum5(x){                                                 var out1 = 0;                 var out2 = 0;                                 for(count=0; count<=x; count++){                         if(count%2==1){                                                         out1+=count;                                 return out1                                        }                         else {                                                        out2+=count;                                 return out2                                 }                        }                 }                                                                                                </script>         </body> </html>```

The proposed function has not two arguments ! Its can't return two values ! Its return a value before to finish the loop !
