Help with finishing a code

[Daisuke_aurora]

Ok. I run a forun where members can RP using a stat system (the custom profile field mod). Basically, members have a set atk power, def power, etc, displayed by the CP field mod. I recently took the Add to post count item and tweaked it to add to the CP fields, and got this:

class item_IncreaseHP extends itemTemplate

{

function getItemDetails()

{

$this->authorName = 'Daisuke';

$this->authorWeb = 'http://www.daisukesdojo.heliohost.org/';

$this->authorEmail = 'Daisuke_aurora@hotmail.com';

 

$this->name = 'Increase HP by xxx';

$this->desc = 'Increase your HP by xxx';

$this->price = 1000;

 

$this->require_input = false;

$this->can_use_item = true;

$this->addInput_editable = true;

}

 

// See 'AddToPostCount.php' for info on how this works

function getAddInput()

{

global $user_info;

if ($item_info[1] == 0) $item_info[1] = 10;

return 'Amount to increase HP by: <input type="text" name="info1" value="' . $item_info[1] . '" />';

}

 

function onUse()

{

global $db_prefix, $ID_MEMBER, $item_info;

 

db_query("

UPDATE {$db_prefix}themes

SET value = value + {$item_info[1]}

WHERE ID_MEMBER = {$ID_MEMBER}", __FILE__, __LINE__);

return 'Successfully increased your HP by ' . $item_info[1] . '!';

}

 

}

 

?>

 

However, there is one problem: The item cannot tell the difference between the 8 CP fields, so it increases ALL of them by 10, not just one. Can anyone tell me how to make it target only one of these fields?
