New Error.. Cant Figure This One Out - php

Question

My timestamp code worked well before i put it in a function.. Get this parse error on line 55, ive marked the line number with "// LINE 55", cant figure it out :(
Here's my error:
Parse error: syntax error, unexpected '.' in C:\wamp\www\flueforumdk\config.php on line 55
Here's the calling of the function:
$GET_UNIX_STAMP_FROM_DB = $art[tidspunkt];
$UNIX_TIME_SECONDS = $GET_UNIX_STAMP_FROM_DB;
echo timestamp_converter($UNIX_TIME_SECONDS);
Here's my function code:
## TIMESTAMP CONVERTER FUNCTION
function timestamp_converter($UNIX_TIME_SECONDS){
// UDREGNING FRA UNIX TIME
$tid = time() - $UNIX_TIME_SECONDS;
$timer = floor($tid/3600);
$minutter = floor($tid/60);
$dage = floor($timer / 24);
$uge = floor($dage / 7);
$month = floor($dage / 30.5);
$aar = floor($dage / 365);
if($tid < 60){
echo"<b>$tid</b> sekunder";
} elseif ($tid > 60){
echo"";
}
if($minutter == 0){
echo"";
} elseif ($minutter < 60){
if($minutter == 1){
echo"<b>$minutter</b> minut";
}else{
echo"<b>$minutter</b> minutter";
}
}
if($timer == 0){
echo"";
} elseif ($timer < 24){
if($timer == 1){
echo"<b>$timer</b> time";
}else{
echo"<b>$timer</b> timer";
}
}
//LINE 55 if($dage == 0){
echo"";
} elseif ($dage < 7){
if($dage == 1){
echo"<b>$dage</b> dag";
}else{
echo"<b>$dage</b> dage";
}
}
if($uge == 0){
echo"";
} elseif ($uge < 4){
if($uge == 1){
echo"<b>$uge</b> uge";
}else{
echo"<b>$uge</b> uger";
}
}
if($month == 0){
echo"";
} elseif ($month < 12){
if($month == 1){
echo"<b>$month</b> måned";
}else{
echo"<b>$month</b> måneder";
}
}
if($aar == 0){
echo"";
} elseif ($aar > 0){
if($aar == 1){
echo"<b>$aar</b> år";
}else{
echo"<b>$aar</b> år";
}
}
}
