If statement inside for loop

I have a for loop going through an array with an if...else statement inside of it, but only the else part is getting read. I want to split the array element into two pieces. if I put the split code in the else statement it will work, but I want to be able to perform the split before the if statement. How do I go about getting this done?

Are we supposed to guess what your code is?

for (var i=0; i < formArray.length; ++i){
        var formArray1 = formArray[0].split("=");
         var formArray2 = formArray[1].split("=");        
          if (formArray[2] >= 65)     {                           
                    document.writeln("Hi  "+formArray1[1]+". At age "+formArray2[1]+" you may retire.") }                    
                     else   {
                                 var formArray1 = formArray[0].split("=");
                            	    var formArray2 = formArray[1].split("=");
 		   document.writeln("Hi "+formArray1[1]+". At age "+formArray2[1]+" you are not ready to retire. Get to work." ) }}

Without seeing what your formArray data is it's difficult to know, but if all your formArray[] elements are key/value pairs joined by '=' then you probably need to split formArray[2] before using it in the if statement.

Either that or your if statement should be checking against formArray1 or formArray2

It is also possible that you never get the if condition satisfied, so every time the algorythm goes to the else statement.

Line 5 seems wrong. If formArray holds keys (names) and values (ages) separated by "=" then formArray1[1] or formArray2[1] could possibly hold a value greater than 65, but formArray[2] never could.

EDIT: Just realized that Chris is saying essentially the same thing.

Thanks Chris, the if wasn't checking against the correct element of the array.
