If you are unable to see the red Submit for approval by primary organisation button, it is likely that your participants/co-applicants have not marked their work as complete.
Here is a screenshot of your application form, the arrow indicates where the Submit for approval by primary organisation button should sit:
In order to enable the submit button, follow these steps:
1. Click into the Summary page of your application form (make sure all pages are Complete) and click the Participants tab
2. If one or more of your participants have an orange Active status beside their name then this means that they haven't clicked the Mark my work as complete button
3. In order to rectify this, please remind your participants that they must press the Mark my work as complete button before their participation is complete
4. Once they have clicked this button, their status will now appear as Complete in your participants tab. Once all your required participants have a green Complete status beside their name, the Submit for approval by primary organisation button will appear
