Follow these steps to re-create the RolloverScript:
Double-click the Scripts object in the Library to open the Symbol Editing window.
Place a keyframe anywhere on the Timeline.
I place my script keyframes so that I can easily read the labels I use, but you can really put the keyframe anywhere.
Double-click the keyframe to open the Frame Properties dialog.
Click in the Label panel and enter the name of the routine. For this example, use RolloverScript.
Select the Actions panel (see figure 08:23). Then pick up again with step 1 in the following section.
