cannot be used with a left hand side of type 'float' and a right hand side of type 'Object'

Assets/Scripts/aniSprite.js(10,32): BCE0051: Operator '>' cannot be used with a left hand side of type 'float' and a right hand side of type 'Object'.

private var myTime :float = 0; private var isPlay = true; function aniSprite (columnSize,rowSize,colFrameStart,rowFrameStart,totalFrames,framePerSecond,totalTime){ myTime += Time.deltaTime;

  if (totalTime!=0 && myTime>totalTime)----------------error--------------how to fix
     {
         isPlay = false;
         myTime = 0;
         return isPlay;
     }
 var index : int = Time.time * framesPerSecond;        
 index = index % totalFrames;         
 var size = Vector2 (1.0 / columnSize, 1.0 / rowSize);
 var u : int = index % columnSize;            
 var v : int = index / columnSize;             
 var offset = Vector2 ((u + colFrameStart) * size.x, (1.0 - size.y) - (v + rowFrameStart) * size.y);     
 renderer.material.mainTextureOffset = offset;       
 renderer.material.mainTextureScale     = size;          
 return true;
