php form mail - checkbox problem

Greetings, Forgive my newbism here, but I am having a hard time recieving check(box)ed items from a form sent to e-mail using PHP. The code is as follows: //Routine for checkboxes $MailBody .="Type medlemskap : "; $items = 2; //initiate possible # of items for ($i = 1; $i <= $items; $i++) { //loop on # of items $MailBody .= "$medlemskap[$i], "; //put results in variable MailBody } ..and the html code put in the form is: <input type="checkbox" name="item_1[]" value="hovedmedlemskap"> hovedmedlemskap [200 kr.] <input type="checkbox" name="item_2[]" value="2 i husholdning"> 2 eller flere i samme husholdning [100 kr.] The problem is, when I recieve the form as email, it just shows the checked item(s) as: ",," (without the quotemarks) What am I doing wrong? I am using the script found here: http://www.grenadine.net/php/NadForm/NadForm_en.html Website where my form is located is here: http://komposlo.inmono.net/m_skap.html Help is very much appreciated! Thanks in advance, Tine
