Tabs

using 1.5.1 and latest tabs

I have both installed correctly and you can see cross sell at bottom of page ,Also tabs are working and have seen 1 or 2 more tabs showing when they were being used .
Except cross sell is not showing at all have now tried both file edits from pages 182 & 183 (also posted on tabs help with no response since 13 feb) with no luck with cross sell ..
Also have tried to get a global option available but every time I try and add the text it crashes the page forcing me to remove it +
I have tried the page edits and can get the basic tab to work but when I try and move the tab it also crashes and tab disappears

any help please as I need to add another tab urgently

I got local help from someone else .For anyone else who wonders why the global editing doesn't work there are "quotes missing" at the end of each sentence on the middle coding with the instructions
see here

// Pre-load Warranty
$fmtShipEst = "\n" . '<div style="width:100%;">' . "\n";
$fmtShipEst .= "This is warranty information for our products. We want you to know that our products have a 100% guarantee." ; (here)
$fmtShipEst .= "Thank you for shopping with us. If you have any questions, call us at 1-800-111-2222." ; (here)
$fmtShipEst .= "\n" . '</div>'. "\n\n";
