    hello,

    I need some help on numbers. I need to get the number for next 
    <?=$row['id'];?>
    PHP:
    and insert into 
    <?=$row['reference'];?>
    PHP:
    this is not a problem. i can do this

    but

    <?=$row['reference'];?>
    PHP:
    number can not be higher than 999. so when 
    <?=$row['id'];?>
    PHP:
    reaches 1000 
    <?=$row['reference'];?>
    PHP:
    should go back to 1.

    When 
    <?=$row['id'];?>
    PHP:
    reaches 2000 
    <?=$row['reference'];?>
    PHP:
    should go back to 1. and so on....


    Can anybody help me please.

    Thanks

    Please explain your problem in more detail, here:
    <?=$row['id'];?>
    <?=$row['reference'];?>

    You are just echoing out the id an the reference i don't see how you are getting or inserting anything

    you need something like
    if (reference > 999){ id = 1 }

    or the other way around...?
    from what I understood you need something like this.?!
    explain some more please.

    but if he changes it to 1 .. then if he ever has to use it again, it will be labeled wrong in the database.
    Better to at least something strange like
    if ($row['reference'] > 999){ id = "1b" }

    then if you ever recall the data you'd have to unwrap it back to a integer.
