What is the actual output of a switch or checkbox? Is it a binary logical, or a text string like “true” or “false”? Any how do we make use of the ‘newvalue’ output? I’m not getting this to work at all.

I tried using the ‘newValue’ directly in an ‘if’ statement and it did not evaluate.

I’m writing ‘newValue’ directly to a label right away to verify that it does change and I get “true” or “false” there as expected.

So I try evaluating the output as text, ‘if (newValue = “true”)’.

But this isn’t working either. Any examples/tips out there?

[[I need help with my check box - #5 by tiny\_apps](https://community.thunkable.com/t/i-need-help-with-my-check-box/3003301/5)  
suggests that ‘newValue’ can be evaluated directly]

So the problem seems to have been with the ‘set property’ blocks. There must have been a stray character in the property field (??). I remade the blocks and it works as expected.

Now to rip out the half dozen special debugging labels and trim all the resulting error blocks…
