Physics.OverlapSphere

No follow-up? What was the problem?

This is what I done in the end and works fine now -

 // Apply damage to the Enemy acording to where they are in the blast radius
 function AreaDamageEnemies(location : Vector3, radius : int , damage : int ){
 
     var objectsInRange : Collider[] = Physics.OverlapSphere(location, radius);
                     
     for (var col : Collider in objectsInRange){
 
         while(i < objectsInRange.length){    // Go through the objectsInRange array (objects in the Physics.OverlapSphere radius)
 
             while(j < myArray.length){    // Check through the myArray array every time the objectsInRange array increases by 1
 
                 if(objectsInRange[i].name.Contains(myArray[j])){    // If there is a match apply damage in respect to where they are in the blast radius
 
 // Linear falloff of effect    
                     var proximity : float = (location - objectsInRange[i].transform.position).magnitude;
                     var effect : float = 1 - (proximity / radius);
                     var enemyNumber = ConvertToInt(objectsInRange[i].tag);    // Extract the number from .name or .tag
 
 // Apply damage to the Enemy
                     switch (j){
 
                         case 0:
                             globalVarsScript.terroristType1Health[enemyNumber] -= (damage * effect * rpgAffectOnTerroristType1);
                             break;
                         case 1:
                             globalVarsScript.terroristType2Health[enemyNumber] -= (damage * effect * rpgAffectOnTerroristType2);
                             break;
                         case 2:
                             globalVarsScript.terroristType3Health[enemyNumber] -= (damage * effect * rpgAffectOnTerroristType3);
                             break;
                         case 3:
                             globalVarsScript.terroristType4Health[enemyNumber] -= (damage * effect * rpgAffectOnTerroristType4);
                             break;
                         case 4:
                             globalVarsScript.sentryGunHealth[enemyNumber] -= (damage * effect * rpgAffectOnSentryGun);
                             break;
                         case 5:

                         case 8:

             }
             i++;
             j = 0;    // Reset the myArray While loop
         }
     }
