Form CheckBox question

Hello, I have this in my form.... the checkUnCheck(this); will uncheck values 1,2,3 if None is chosen... Now when I submit this form, the output I get from $Avail is the word Array and not the actual content.... ('1,2,3' if I choose 1,2,3) <td> <input type="Checkbox" name="Avail[]" value="1" onclick="checkUnCheck(this);">1&nbsp; <input type="Checkbox" name="Avail[]" value="2" onclick="checkUnCheck(this);">2&nbsp; <input type="Checkbox" name="Avail[]" value="2" onclick="checkUnCheck(this);">3&nbsp; <input type="Checkbox" name="Avail[]" value="" onclick="checkUnCheck(this);">None&nbsp; </td> Am I missing something?? And no, I'm not a very experienced PHP developer. :-) Yves Arsenault Carrefour Infotech 5,promenade Acadian Charlottetown, IPE C1C 1M2 yves@carrefour.peicaps.org (902)368-1895 ext.242 ICQ #117650823
