Small problem with producing a small 2 bar bar graph

[JSX]

Hello everyone, im having a really frustrating problem trying to make my graphs physically show the bars for the graph, from what i can see there are no problems with the code! but i get red x's rather than 2 bars being drawn. If anyone could shed some light onto this i would be much appreciated, i know my php version is compatible with graphics and i am using jpeg not gif images so really dont understand what could be wrong. the code:

Any help be much appreciated! :)

[code]<?php
//Produce function to call graph generation file gd.php and round percentage values to 2 decimal points to displayed beside the graphs.
//Then multiply the values for the two bars by 200 to determine the height in pixels of the bars.    

function  graphic ( $blueval , $redval ){  
$percentrd  =  round($blueval * 100,2 );  
$perccentbl  =  round($redval * 100,2 );  
$blueval  = ( $blueval * 200);  
$redval  = ( $redval * 200);  


echo  "<table><tr><td align= \"center \" >$perccentbl%</td><td>
<img src= \" gd.php?bluehg=$blueval&redhg=$redval \"  height= \" 100 \" >  
</td><td align= \" center \" >$percentrd%</td></tr></table>";  
}  

// Create  layout for graphic display and call the graphic () function  

echo  "<tr><td colspan=\"4\" align=\"center\"><table cellpadding=\"10\" border=\"1\" bgcolor=\"#B0E0E6\"><tr><td align=\"center\" valign=\"center\">";  

graphic ( $onsiteval , $offsiteval );  

echo  "</td><td align=\"center\" valign=\"center\">";
?>[/code]


The gd.php file it calls below....

[code]
<?php

Header ( "Content-Type: image/jpeg" );

// Create a 10x200 image

$im  =  ImageCreate ( 10,  200 );
// Create Colour Pallette
$red  =  ImageColorAllocate ( $im,  255,  0,  0 );
$blue  =  ImageColorAllocate ( $im ,  0 ,  0 ,  255 );
$grey  =  ImageColorAllocate ( $im , 0xC0, 0xC0 , 0xC0 );

//Fill Background of image as grey

ImageFill ( $im , 0 , 0 , $grey );

ImageFilledRectangle ($im , 0 ,0, $bluehg, 200, $blue );

ImageFilledRectangle ( $im , 6, 0, $redhg, 200, $red );

Imagejpeg($im);

?>[/code]

I can only assume that the GD library is installed and enabled?

Are you getting any errors?

BTW, Welcome to the forums.

Hi thanks for the welcome! yep the gd libary is installed and from what my admin said i assume is enabled.

I get no errors whatsoever, just red squares for output instead of the graph like so, it is really puzzling me!
Here's what im getting lol
