Unable to Enable Attachment for Custom Form.
We have developed a custom form and we are trying to enable the attachment functionality on the same but are unable to do so. I request you to please let me know the perquisites required by you to check where I am going wrong. I have entered the values that are shown in the attached file to enable the functionality but still there was no success. Following things are already done, 1. In custom block,open the trigger "WHEN-NEW-BLOCK-INSTANCE" and modify Execution Hierarchy of Trigger at Custom Block from Override to Before. 2. Profile option 'Indicate Attachment' set to Yes at Site level.
