Folks,
I know this has been asked before, and I have read the documentation on resetting custom fields, and looked through the forum, but still cant get it... I know it is something small, but as a newbie, I just cant see it.

I have a form called "My Form", with a Dropdown called "Field A"..... which has entries called "Ent 1", Ent 2", "Ent 3", "Ent 4" as the dropdown values.
I have 2 checkbox groups:
"Chk 1", (with 3 checkboxes), (conditional on "Field A" = "Ent 1"), and
"Chk 2", (with 4 checkboxes), (conditional on "Field A" = "Ent 2") (not worried now about "Ent 3" & "Ent 4"

If "Field A" = "Ent 1", I want to reset "Chk 2", and if "Field A" = "Ent 2", I want to reset "Chk 1"

I have the following code in the $Post_Form area, but I can't get it to work.... can anyone spot the obvious error which I cant see due to my ignorance?

if ($_POST == 'Ent 1')
{
unset($_POST);
}
if ($_POST == 'Ent 2')
{
unset($_POST);
}

Thanks folks,
Mike

Any thoughts folks?

thanks,
Mike

Hi Mike,

Accessing the values from $_POST can be done in the Scripts called during the form process like this:

Please note that if you are trying to access a dropdown's value you need to add the index like this
More information on PHP Scripts can be found here:

Thanks for that Cosmin... I will check it out and try to get this working... the "$_POST[0]" is a great help... I didnt realise that (must have missed it in the documentation).

thanks again,
Mike
