Activating third block not working

[fervaldies]

Hello, I am trying to activate three blocks, each of them after a certain amount of time in the simulation. For the first 2 blocks everything is working and the heat conduction and heat source are correct, but when I try to activate the third block (after 640 seconds) the block does not activate its properties. This is part of the input file:

I wonder if the u_threshold_2 is executed after the _3 and disabling the kernels::xyz3 objects.
Let's try to chain them.
Add the depends_on parameter. 3 depends on 2, which depends on 1

Thank you for your answer. I have tried this, but no the first two conditions are not acting at all and it is only after 640s that the third one is activated:

Okay I think it is working now. I just disabled the previous conditions and created new kernels that are activating the 2 or 3 blocks for each time, rather than having different kernels that only activate one block each. Thanks!
