Hi.

If I understand correctly, you want to validate some input, and display warnings if they are incorrect?

Do you mean something like this?
[code=php]
if(substr($sn,0 ,1) != "S") {
echo '<script>alert( "Your input must start with S");</script>';
}
else if(substr($add, 0,2) != "00") {
echo '<script>alert( "Your input must start with 00");</script>';
}
else {
# The input fields are valid. Do whatever you want to do.
}
[/code]

Heya, cyberlei.

You need to re-balance your curly braces.

The proper syntax of an if ... else is:
[code=php]
if( $condition )
{
// Do this if $condition is true.
}
else
{
// Do this if $condition is false.
}
[/code]
