Assuming all your page items are on separate rows, under your Page Attributes Header and Footer section, add the below function under Header Text:
<script>
function f_toggleNM() {
   // if P2_ATTACHMENT_TYPE value is D, then show row holding P2_CUSTOM_NAME and P2_CUSTOM_MSG. Else hide them
   $f_Show_On_Value_Item_Row('P2_ATTACHMENT_TYPE', [ 'P2_CUSTOM_NAME', 'P2_CUSTOM_MSG' ], 'C');
   // if P2_ATTACHMENT_TYPE value is C, then show row holding P2_DEFAULT_NAME and P2_DEFAULT_MSG. Else hide them
   $f_Show_On_Value_Item_Row('P2_ATTACHMENT_TYPE', [ 'P2_DEFAULT_NAME', 'P2_DEFAULT_MSG' ], 'D');
</script>Under Footer Text, add the below:
<script>
f_toggleNM();
</script>And on the P2_ATTACHMENT_TYPE item, Element tab, HTML Form Element Attributes, add below:
onchange="f_toggleNM();"Hope this helps. Thanks!
