TSVarList not populating

I am trying to populate a TSVarList based on a choice input. XApplications is populated when using an AppTree but not with ChoiceInput. am I using this correctly? My goal is to select applications without user interaction.

<Action Type="TSVarList" ApplicationVariableBase="XApplicationsB">

    <SoftwareRef Id="54945a55-5003-42b6-a9ec-38abbb318bc4" Condition='"%CSGChoice%" = "IMSupport"' />

    <SoftwareRef Id="e3c5060c-bc26-40b0-9901-4e68fe1f1a26" Condition='"%CSGChoice%" = "HRSupport"' />

</Action>


Thank you in advance
