Tab Index running into order

Hi, I have tab index values assigned to different fields on my page. When I run the application, and tab through the fields, they are not moving in order. Any idea what could be causing tabs disorder? Thanks!

Without having any context it is hard to desribe what is causing this. So my advise it to set them all back to 0 and start over, one by one, see when you start getting some difficulty.

It is not possible to have overlapping numbers, since that would show up in the errorlist. (also in 5.21.1? not sure)
