Hi, not been writing code for a while, how do I add  && in a dynamic binding

this is the code 

<s:CheckBox id="overlapCheckBox"
         scaleX="1" scaleY="1"
         selected="{data.overlapReading}"
         horizontalCenter="0"
         verticalCenter="0"
         visible="{data.accountType != 1 }"
         click="changePlacement(event)"
         skinClass="com.peach.uofs.common.StudentPlacementCheckBoxSkin"/>


i want  visible="{data.accountType != 1  && data.aPage  }"
