2 mysql INSERT statements at same time?

Hello,
I would like to take one post and insert it in 2 differet tables in mysql.

I thought this would work, but it either inserts the first one or the second one. Can anyone help?

$sql=“INSERT INTO da_polls (Title, Description, Usrid, Group_ID, Value_1, Value_2, Value_3, Value_4, Value_5, Time)
VALUES (’$_POST[Title]’,’$_POST[Description]’,’$_POST[Usrid]’,’$_POST[Group_ID]’,’$_POST[Value_1]’,’$_POST[Value_2]’,’$_POST[Value_3]’,’$_POST[Value_4]’,’$_POST[Value_5]’,NOW())”;

$sql=“INSERT INTO da_conversations (Title, Description, Usrid, groupid, Time)
VALUES (’$_POST[Title]’,’$_POST[Description]’,’$_POST[Usrid]’,’$_POST[Group_ID]’,NOW())”;
