    Also can be usefull with many trigger actions.

     

    Steps:

    1. Create a variable vClearButtonHit;

     

    2. Set this expression for it:

    =if($(vClearButtonHit)-isnull(GetCurrentSelections())>10,0,$(vClearButtonHit)-isnull(GetCurrentSelections()));

    [this condition will increase variable value till it under 10, after that the value will be droped to zero]
