HI All, I have a scenario I can’t seem to solve, I have a series of check boxes that can be selected in a random pattern. I have a button that “deselects” them all and a button that “selects” them all. The check marks disappear when deselected, but I can’t seem to get the check mark to appear when “select all” button is clicked. I set the selected value to “1”. is there another step I need to do? Regards, Gareth ---

Try using True and False instead. If that doesn't work then please post your code for both buttons. See [Wiki - how to post code on this forum](https://forum.inductiveautomation.com/t/wiki-how-to-post-code-on-this-forum/77831). ---

Perspective's backing property model is [JSON](https://en.wikipedia.org/wiki/JSON), which has numbers, strings, and true booleans. `1`\[1\] is not the same as `true`\[2\] is not the same as `"true`"\[3\] is not the same as `"1"`\[4\]. * * * 1. a number 2. a boolean 3. a string containing four letters `t, r, u, e` 4. a string containing the numeral `1` ---

Thanks Paul, I appreciate this, I was getting a bit confused, I’ve used C and C# and a few other languages where 1 and 0 and true and false are interchangeable and the keyword is lowercase. I am new to JSON and Python, some of it is familiar and some not so much. This forum is a great tool and people are very generous with their knowledge. Regards, Gareth ---
