Hi guys, I feel like this is going to be a stupid question but here goes nothing. In my project I want to make use of system.gui.confirm / errorBox / warningBox but I cannot for the life of me figure out how to implement it - maybe I am just missing something obvious. As a test I created a temp function that counts the amount of times someone tried to navigate to a page I am still working on a throws a message that the screen isn't available with a count of how many people tried. If I run the code in the designer/script editor I get the popup box as I want, then I copied the code to the gateway script library and if I call it from the script editor I get the popup. But if I try to paste the code in a button event script or call the gateway script from a button event I get the error that system.gui doesn't exist. Can someone please point me in the right direction. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/2/4/242e362e96ec10def92a8c9673eddfe95252432c.png) EDIT: ```python def screenNotReady(clicked): links = { 'bereiding' : '[default]Project_Variables/ScreenNotDone/Bereiding', 'silos' : '[default]Project_Variables/ScreenNotDone/Silos', 'branderij' : '[default]Project_Variables/ScreenNotDone/Branderij', 'molens' : '[default]Project_Variables/ScreenNotDone/Molens', 'verpakkerij' : '[default]Project_Variables/ScreenNotDone/Verpakkerij', 'logistiek' : '[default]Project_Variables/ScreenNotDone/Logistiek' } var = system.tag.read(links[clicked]).value var += 1 message = "Congrats, you are the ###th person to try...\nNo this screen is still not ready!" message = message.replace('###', str(var)) system.tag.write(links[clicked], var) system.gui.warningBox(message, "Oooooof") ``` ---

Post code, not pictures of code. It helps speed up the testing process as people can copy/paste instead of having to try to read a screenshot. Please see [Wiki - how to post code on this forum](https://forum.inductiveautomation.com/t/wiki-how-to-post-code-on-this-forum/77831). You can edit your post by clicking on the pencil icon in the bottom right. Moving on, you have this marked as perspective. `system.gui.warningBox` is vision only. (I personally recommend rolling your own info popup in vision as well) ---

System gui isn't available in a perspective scope. Only for vision. You will have to roll your own. ---

Separately from the immediate issue (`system.gui` and `system.nav` should really be `system.vision` functions), some other things I notice in your script: 1. Tags are often not the right place to store user interface information, unless you truly do want _global_ storage of variables. 2. Use string.format, not replace for nicer to read and write string templating: [https://pyformat.info/](https://pyformat.info/) 3. Repeat yourself as little as feasible, e.g. your dictionary of `links` is essentailly just repeating keys -\> values with a static path prepended. ---

Seems like something easy to miss that only Vision is supported. Makes sense why I couldn't get it to work. Thank you for the reply, I will create my own. Thank you for the other feedback PGriffith ---
