Sendmail limit ?

May I ask...when I want to list a html table as below coding to show all the results of picklist (around 30 individual picklists),
it failed when there are more than 30 picklists..

html = html + "<tr><td>Item Name</td><td>Price</td><td>Qty (=input.picklistA)</td></tr>";

Item Name <- Is it have a way to let me call them as this is the displayname of picklist such as input.formdata done ?

I have tried to rewrite from
http://help.zoho.com/portal/en/community/topic/can-the-sendmail-from-a-form-only-send-data-from-the-decision-checkboxes-selected-by-the-user

But I don't know how I can save the items data(Name, Price, etc) and call them out....please help ;; THX ALL GUYS
