Hi Harish,
We tried copied these two lines into our CF7 form and it didn’t work:
<input type=”hidden” name=”_mc4wp_lists” value=”532265″/>
<input type=”hidden” name=”mc4wp-GROUPINGS[38309]” value=”Test”>
For some reason, if we take out the second line, it’ll add the person to the list, but once we add in the second line, neither work.
