Please help on a button question

[Findarato]

I created a new button style and its not working. All I get is a black square where the graphic should be.

I basically copied the code for the find button from the group window and then just altered the name and images.

<?xml version="1.0" encoding="utf-8"?>
<Page Name="vert_styles" ScrollExtent="320,240" Size="320,240" Visible="false">
<Namespace Name="kbookprev">
<ImageStyle Filter="true" Name="p_button_normal">
<ImageFrame Name="image" Source="images/solspellbook02.tga" SourceRect="3,4,83,21"/>
</ImageStyle>
<ImageStyle Filter="true" Name="p_button_pressed">
<ImageFrame Name="image" Source="images/solspellbook02.tga" SourceRect="3,43,83,60"/>
</ImageStyle>
<ImageStyle Filter="true" Name="p_button_rollover">
<ImageFrame Name="image" Source="images/solspellbook02.tga" SourceRect="3,23,83,40"/>
</ImageStyle>
<RectangleStyle Center="minimize_button_normal" CenterShrinkH="true" CenterShrinkV="true" Name="p_but_normal"/>
<RectangleStyle Center="minimize_button_pressed" CenterShrinkH="true" CenterShrinkV="true" Name="p_but_pressed"/>
<RectangleStyle Center="minimize_button_rollover" CenterShrinkH="true" CenterShrinkV="true" Name="p_but_rollover"/>
<RectangleStyle Center="minimize_button_normal" CenterShrinkH="true" CenterShrinkV="true" Color="#808080" Name="p_but_disabled"/>
</Namespace>
<ButtonStyle Name="KB_prev" RStyleDefault="kbookprev.p_but_normal" RStyleMouseOver="kbookprev.p_but_rollover" RStyleMouseOverActivated="kbookprev.p_but_pressed" RStyleMouseOverSelected="kbookprev.p_but_rollover"/>
