InfoPath Drop Down list, loses data after trying to submit

Question

I have a question about my InfoPath Form:

When I select a value from the first Drop Down list, the second one appears (it has a hide rule) and it has the values I configured in the InfoPath.

But when I select a value from the first Drop Down list and do not click on the second one, I get an error!

After this, I submit the form and the forms needs a value from the second Drop Down. So, after this message, I clicked in the second Drop Box, but all the values are gone.

If I exit the form, and open it again, the forms loads OK and if I repeat the same actions, the data of the second Drop Down list disappears again.

Answer 1

Problem solved guys! I changed the button of Infopath, before it was reading the a rule for submit, now the button is a submit button!

Hope this can help someone!
