Distance before shooting issue.

I can't get the AI to shoot at the correct range which is referenced from another script called RifleAI.

Well it works almost perfect if I type in a number but not if I put in the float range.

Let me explain in Code:

// This is where the range is referenced from aka the rifle script.

 private Rifle weaponRifleScript;
 
 
 void Update(){
 
    if(canShoot == true){
 
       Shooting();
 
      }else{
 
       canShoot = false;
 
 }
 }
 
 
 void Shooting(){
 
   targetDistance = Vector3.Distance(player.position, target.position);
 
   // this is where it gets the range from the rifle script.
   float range = weaponRifleScript.range;
    
   if(targetDistance < range){
 
     weaponRifleScript.InvokingRepeating("Shoot", 0.5f, 20);
 
 }
 }

So yeah, its simply not working, either it shoots from what ever range or does not shoot at all.

Heeeelp....
