Stopping a StoryBoard

Question

I am trying to mimic a game of bingo (lotto) and i am having problems with my display grid. The way i have done it is by showing a design for 1 - a number not called (notCalled) 2 - the number which is being called (myLabelJustCalled) 3 - numbers that have been called in the past. (myLabelCalled)

The issue of have is when the number is called i have animated it to spin in a circle however when it changes to the style 3 the next number (which should take on style 2) does not spin it freezes. I think i need to stop my storyboard and rerun it with the new label.

Hope this makes sense!

code attached:

    <Label Name="labelNumber" Content="{Binding Number}" Height="50" Width="70"/>

<Style x:Key="numberDesign" TargetType="{x:Type Label}">
    <Setter Property="Foreground" Value="Red"/>
