Inserting a sub-form more than once is not possible in Notes. To overcome this limitation apply the below technique. This technique will be useful in the case of header information (say a logo) needs to be added in the footer also. Instead of creating another sub-form you can use this technique to achieve the same. Make sure that there are no fields available in the sub-form. (Field with the same name can't be inserted more than once).
- Insert a computed sub-form and give the sub-form name as input to the Computed sub-form.
- Insert the same sub-form directly in to the form.
- Compose the form. You can find the same sub-form will be appearing twice.
Note: If you do the other way, by first inserting subform directly and inserting a computed subform leads to error.
