[code=php:0]
<?
if($profile['customt1']==0){
echo "gah";
}else{
?>
<tr><td valign="top"><b><? echo "$profile[customt1]"; ?></b> </td>
<td valign="top"><? echo "<p>$profile[customtext1]</p>"; ?></td></tr>

<?
}
if($profile['customt2']==0){
echo "gah";
}else{
?>
<tr><td valign="top"><b><? echo "$profile[customt2]"; ?></b></td>
<td valign="top"><? echo "<p>$profile[customtext2]</p>"; ?></td></tr>

<?
}
if($profile['customt3']==0){
echo "gah";
}else{
?>
<tr><td valign="top"><b><? echo "$profile[customt3]"; ?></b> </td>
<td valign="top"><? echo "<p>$profile[customtext3]</p>"; ?></td></tr>

Post the code where you get $profile

[almightyegg]

Well, I know it isn't wrong with that as I have used else where but here:

[code=php:0]
$id = $_GET['id'];
$first = "SELECT * FROM users WHERE id = '$id'";
$second = mysql_query($first);
$profile = mysql_fetch_assoc($second);
[/code]

[Jessica]

Under that, do print_r($profile); and see what it says for customt1. Paste the print_r() result here?

[customt1] => Music
It recognises it fine, all of the bits im trying to do come out fine  ???

[Jessica]

Instead of comparing it to 0, try checking if it is set.
If I recall correctly,
if($profile['customt1']==0){
Will convert $profile['customt1'] to a number. Since it's not a number, it turns into 0. Thus, TRUE.

Try

if(!isset($profile['customt1'])){
// gah
}

[almightyegg]

stops all info from being displayed.... :-[

[Jessica]

Now it doesn't display gah or your table?
What about

if(empty($profile['customt1'])){

[steelmanronald06]

it will have to be something like:

if (!$profile['custom1'])) {

echo 'gah';

}

Granted empty might work to, but I use the ! and it works fine on my sites.
