Re: [WEB400] How Do I Keep IE From Saving Values

[Tom Jedrzejewicz <tomjedrz@xxxxxxxxx>]

Very slick - elegant solution.

But, don't you need a VALUE on the CCFIELD to actually hold the random
value generated?

<INPUT name="CCFIELD" TYPE="HIDDEN" VALUE="/%CCFIELD%/">
<INPUT name="/%CCFIELD%/" TYPE="TEXT" SIZE="16">

Take care.
