Hello, I have been working on a flow that helps to automate an indexing application I use at work. I have it currently working so that it prompts me to enter an acceptance code in a Display Input Dialogue box, but I want to share this flow with coworkers and make it a little more airtight. Can I make it so it can recognize if the code entered isn't a valid acceptance code, and re-prompt the user to enter a new code? A valid code would be 7 digits, OR "ACC" followed by 7 digits. A code doesnt NEED the ACC, after being validated, so that portion can be removed from the code. Any help would be appreciated. It look a lot of trial and error to get this far, and am in need of aid. Below is a snip of the relevant portion of the flow I use
