bryan, I thought for sure I read that you couldn't store complex vars in a cookie.....but I guess a wddx packet can really be percieved as a string, and if the length works, then it will be ok....but not really the best way to do it...huh?

Follow these steps: 1) form is posted 2) create a new query using QueryNew() 3) add a row to the query using QueryAddRow() 4) add all the form data to the row in the query usingh QuerySetCell() 5) serialize the query into a WDDX packet using CFWDDX 6) set a cookie with the value of the WDDX packet using CFCOOKIE Then wherever you need the data..... 1) deserialze the WDDX packet in the cookie 2) voila you have a query with all form data in it 3) do whatever ya need to to re-create your form as it was left HTH Bryan Stevenson B.Comm.
