JavaScript / Google Apps Scripting - Write function to calc dates

Write a function for Google Apps Scripting to run in a Google Drive spreadsheet. Function takes input of birth date and calculates if a person is young enough to be eligible, using two rules. I think the comments below explain, but send me any questions. Write functions to accept DOB as y,m,d integers and another to accept one input of date data type ** Google Apps Scripting - function will be copy paste into an existing Google Apps Spreadsheet script with other functions. Deliverable is the code I can cut paste into my scripts for the sheet. function exrAgeEligibleInputInts(intBirthYear,intBirthMonth,intBirthDay,bolPerformed){ // Age eligibility calculator using input Date of Birth as ints for year, month, day // Season is June 1 to Aug 15. Function calculates for 2014 season // No musician over the age of 21 may participate in a performance. // exception: // A musician that participates in at least one performance during the season while age 21 and turns 22 during the season my complete the season. //Returns one of three strings // "Eligible // "Eligible by exception // "Not eligible } function exrAgeEligibleInputDate(dtDateOfBirth,bolPerformed){ // (same as above) using one input param of DOB as date type }
