Hello
I'm a newcomer to the site so please forgive me if I post messages
incorrectly (and please tell me how to do it properly!)
Am I missing something obvious, or can you simply use the abs() function
to obtain the absolute value of the number? This could be combined with the
function is_numeric() to do the validation on user input that you need.
I hope this helps

Hi Paul,
abs() was fine, mostly it was just me having a blank moment and completely
forgetting about the command after a seriously long day programming.
it came out in part like;
if(!is_numeric($height)){$height = $oldh;} $height = abs(intval($height));
if(($height < 70) || ($height > 768)){$height = $oldh;}
ultimately.
Nothing I can see wrong with your posting, more the merrier!
