Since every new record is a standalone INSERT query you might be better off counting manually by incrementing a variable? [CODE] $count = 0; while(){ mysql_query("INSERT into.......") or die(mysql_error()); $count++; } [/CODE]

This is what you should do: [CODE] //set counter $a = 0; while(){ //check if counter is at start (0) if($a == 0){$results .= '<div class="result"><p>';}//Display at start of a block of 4 results $a++; $results .=''.$result.''; if($a == 4){ //reset counter so it is as start again $ = …

[QUOTE=cwarn23;1130055]What do you mean by "run a muck"? I thought it would be wise.[/QUOTE] It was wise of you to let us know - but not everyone on this site is wise.... or nice! Gratz on nearly cracking it though

in what format do you store your check_in & check_out data? If its a timestamp you can make a comparison between them but if is like 1 Jan 2010 you might have some trouble making a comparison.

a way to avoid the error would be to check if it exists before unset() - also setting the value to NULL or FALSE. if(isset($_SESSION['credit_total'])){ unset($_SESSION['credit_total']); //$_SESSION['credit_total'] = false; //$_SESSION['credit_total'] = NULL; }

Php has no problem with HTML tags the problem lies in the header the email is sending out - it is not telling the mail program that the email contains HTML. emhmk1's solution should give you what you are looking for.

You could set the values in sessions or hidden form fields and then process them at the end(this method is inadvised for secure information).

Think this is it, just apply your db info to teh $db_text variable; [CODE] $db_text = $db_info[text]; echo substr($db_text, 0, 400); if(strlen($db_text) > 400){ echo "........ Read More"; } [/CODE]
