请教 变量被覆盖应该怎么解决

在maya中执行mel提示错误

for ($vert in $verts)

{


    if (`progressWindow -q -isCancelled`) 
    {
        $aborted = yes;
        warning "松弛顶点被终止.请撤消最后一个操作.";
        break;
    }


    float $pos[] = `pointPosition $vert`;
    
         move $pos[0] $pos[1] $pos[2] $locator[0];
    

    float $pos[] = `pointPosition $locator[0]`;
    
    move $pos[0] $pos[1] $pos[2] $vert;
    
    
    progressWindow -e
        -status ("Relaxing " + $vert + " of " + $numberOfVerts)
        -step 1;
}


progressWindow -endProgress;

// Warning: Line 157.45 : Redeclaration of variable "$pos" shadows previous declaration at line 152. Previous value will be overwritten by explicit initializer.
