Unable to add read and write role to variables

[samadam]

I am trying to add make a catalog item available to public with out login. I can see the catalog item but not the variables. I am not able to add the read and write roles. Is there anything else that needs to be set for this to work?

ensure the item has "Available for all users" checked then ensure the variables' visibility is set to public by and clearing any Read/Write roles on the variables and Verify the "Visible" checkbox is enabled.

check and modify ACLs for sc_item_option and sc_item_option_mtom tables to allow public access and last confirm the guest user has appropriate permissions for accessing variables.
