Hi Dave, Can you please explain some more in detail when you are getting free time, how did you implement that?. Becoz my application is accessed via web browser. Users are adding attachments via display only form and i am having an audit form (Regular form) to store this values. In the properties of attachment field, if i delete add label the attachments buttons are invisible. After i create our own customized button, i don't know how I could precede further. It would be great help for me if you share this info.
Hi Carry, Attachment field name on the display only form and in regular form is "EPW Table" 4 attachments in this pool, their names are Purchase Approval Quote Order Form Deviation Form This is identical both is display only and regular form Is it possible that your filter it trying to test for a data change in the Attachment Pool instead of the correct attachment field? Yes, i am testing the particular attachment is updated or not. Please let me know if you need any further input on this.
