Switching Tabs & show custom view.

[scoffy]

I am very new to this, so sorry if i am asking silly questions.

I have a tabbed application with 3 tabs.

The first tab is just for the home screen, the second is to view entries & the 3rd is to edit the entry details.

To add a new entry (3rd tab) the user needs to progress through 3 steps, where they select a date(root), a category & then the final screen where they enter the details.

On the second tab users are able to view the entries they have made. If a user chooses to edit an entry i want it to switch to the 3rd tab & show the 3rd screen with all the details as all the details from step 1 & 2 will be transferred from the entries page.

The reason i want it to behave like this is because users will need to refer back to all the entries while filling the detail out.

I can't figure out how to accomplish this. What is the best way to get this done? Any examples would be great.

thanks.
