I want to display a tick mark on slide tab when the tab slides are seen by the user

[ashj62748129]

I have tabs/sections on the left hand side of each page/slides.

Each tab consists on 2-3 slides. After one tab's slides are completed next tab gets activated automatically and its slides run and like that all tabs get completed. I have copied all 7 tabs/buttons in each slides. The requirment is when the user completes a section. For example "introduction" is completed after all 3 of its slides get completed. In that case on the "introduction" tab there should be a tick mark to indicate that its completed.

For your reference attaching images over here

Expected output:(tick marks on the tab based on slides completion)

Please help. I ried many advanced actions but its not working. I would appreciate if you could provide a step by step solution. Thank you in advance.

More information is needed. Those 'tabs' are not acting as buttons? How do the learners navigate to next slides, do you have a Next button on each slide? Because any action needs a triggering event, which can be the Success event on a button.

You have a copy of those 'tabs' on each slide? They are not timed for the rest of the project or on the master slides?

For the tick mark, I would add a custom state to the tabs, duplicate of the Normal state  with tick mark as added object. How to change the state depends on answers to my other questions.
