The green `newValue` block will have a value of true or false. So you need to see if newValue = true or newValue = false. You’ll find the true and false blocks in the Logic drawer. Don’t use the `Visable` or `Disabled` property blocks for this. ---

As tatiang said … use the “value” block instead of visible or disable… exactly the way you did it . you “don’t need” to use logic blocks. ---

Hi @tagewiberg10mi you have to replace your true and false blocks with the green newValue (thsi block returns true or false depending on the checked state of the checkbox) block and instead of using two if statements you can use a if else statement. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/d/0/d0647670be3807f6533ae98c5e006abac3dbedfa.png) edit: Ive shared the wrong code, my appologies. Button’s 4 text returns a string so adding a number to it won’t work, using a number variable and placing your blocks like this should work. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/5/0/505e41bfa510ba55284d5633a3b019987e384d43.png) ---
