Movie clip linkage

Hi

I not sure if I’m doing this right. I have a holder movie on my timeline called “background”.
When entering a certain frame I want this background movie clip to be replaced with one linked in the library. This is what I have in the frame but its not working.

this.background.attachMovie(“shop_bg”, “deafwife_bg”, 1);

**deafwife_bg is **the linkage name.

Am I doing something wrong? :hurt: Cheers in advance
