I have a series of movie clips named Imagex\_y where x is the number of the current test and y is the number of the current question.  
In as 2 I have a for loop as such:

```auto
for (i=0; i<=6; i++) {
        this["MCNAME"+i+"_"+questionnumber].visible = false;
    }

```

When I attempt to run the code above I get an error in the compiler as such:  
TypeError: Error #1010: A term is undefined and has no properties.  
How can I get this code to work in as3.0?
