Picture HP Display

For my game, I'm trying to have the HP (and the faceset) display on the screen... I made pictures for it and made a common event for it to show up, but...it's not working for some reason. Here's my code (Note: There are three common events):

Health=Fine
-------------
<> Fork Option: Variable [0009:HP]-75 Over
<>Show Picture: 1,Fine, (160,120)
<>
:End Case
<>



Health=Caution
-------------
<> Fork Option: Variable [0009:HP]-50 Over
<>Fork Option: Variable [0009:HP]-75 Less
<>Erase Picture: 1
<>Show Picture: 2,Caution, (160,120)
<>
:End Case
<>Show Picture: 1
<>
:End Case
<>



Health=Danger
-------------
<>Fork Option: Variable [0009:HP]-50 Less
<>Erase Picture: 1
<>Erase Picture: 2
<>Show Picutre: 3
<>
:End Case
<>




Can anyone help? (Note: I am using RM2k)
