Stablish Dependecies in Zoho Project Template

Stablish Dependecies in Zoho Project Template

Hello,
I have created 1 project template, some task lists and on each task list, some tasks with its subtasks.
All tasks and subtasks are configured with duration=0 and star tafter=0, this is a project template and at this moment I don´t want to setup this. This values will be introduced when I create the "real project" using the template.

I am trying to setup dependencies in the project template, but it is impossible, always errors with dates.


Where is the problem?

Note.- I have attached a screen capture to this topic, please check.

Regards,
Unai
