Code: Select all
<?php
$wheelsize = $_POST['wheeldiameter'];
$tyrediameter = $_POST['tyrediameter'];
$tyrewidth = $_POST['tyrewidth'];
$inch = '25.4';
$sidewall = $tyrediameter - $wheelsize;
$tyrewidthmm = $tyrewidth * $inch;
$sidewallmm = $sidewall * $inch;
$profile = $sidewallmm / $tyrewidthmm;
echo 'Your tyre size is '$tyrewidthmm'/'$profile' '$wheelsize ;
?>
Please could someone correct this for me. Where abouts does it need a ',' or ';' in line 13?

You're not concatenating the strings with periods. Try this:
Code: Select all
echo 'Your tyre size is '.$tyrewidthmm.'/'.$profile.' '.$wheelsize ;

You can simply write the vars into the text string when you use double quotes.
Code: Select all
echo "Your tyre size is $tyrewidthmm/$profile $wheelsize" ;
if you want to use the single quotes then you need to concatenate the vars into the string with the . concatenation operator
Code: Select all
echo 'Your tyre size is '.$tyrewidthmm.'/'.$profile.' '.$wheelsize;
