contacts

survey answers

respondent_initial

respondent_no.

respondent_initial holds input from a webform where I populated it with the custid from contacts and respondent_no from survey answers before the webform input is inserted.I want to send an email to them that had there respondent_no in a hyperlink to the webform so that when they entered their data into the webform it would use the repondent_no to determine where to insert the form data.

Example joe clicks http://www.myplace.com/order.aspx?23

Mike clicks http://www.myplace.com/order.aspx?125

it would look up respondent_no (23) from the respondent_initial table and insert the data in that row in the database for joe's webform entry and it would look up respondent_no (125) from the respondent_initial table and insert the data in that row in the database for mike's webform entry. my code behind looks like this

// Create command
comm = new SqlCommand("INSERT INTO respondent_inital (Practice_Name, Address1, Address2, City, State, Zipcode, Phone, Email, Contact, Dealer, item_9223, item_9129, item_42795, item_30695, item_42834) VALUES (@Practice_Name, @Address1, @Address2, [code]....
