Screenshot problem

When i try to take a screenshot either jpg or png i ge tnothing but a file that is light blue nothing actually in the file. here is my screenshot.cs from common/client.

//----------------------------------------
$screenshotNumber = 0;

function doScreenShot( %val )
{
if (%val)
{
if ($pref::Video::screenShotSession $= "")
$pref::Video::screenShotSession = 0;
if ($screenshotNumber == 0)
$pref::Video::screenShotSession++;
if ($pref::Video::screenShotSession > 999)
$pref::Video::screenShotSession = 1;

$pref::interior::showdetailmaps = false;
$name = "screenshot_" @ formatSessionNumber($pref::Video::screenShotSession) @ "-" @ formatImageNumber($screenshotNumber++);

if($pref::Video::screenShotFormat $= "JPEG")
screenShot($name @ ".jpg", "JPEG");
else
if($pref::Video::screenShotFormat $= "PNG")
screenShot($name @ ".png", "PNG");
else
screenShot($name @ ".png", "PNG");
}
}


// bind key to take screenshots
GlobalActionMap.bind(keyboard, "ctrl p", doScreenShot);


i have done a search and cant find anything for a fix or if something is wrong here. can someone who's screenshots working see if this section is the same?

looks like one line continued after i pasted which i already know
