Based on what’s included here, it’s possible that the issue might be occurring due to the regular expression not being correctly configured. It seems from your screenshot that you are using the regex validator in the text field of your variable configuration. This may only validate if the input matches the regular expression, rather than extracting the matches from the string. Ensure the configuration is correctly set to extract matches from your Form Element string. Furthermore, check how you are recalling your variable in your code, as this could also be a potential source of the issue. If possible, try to provide a little more context or code snippets for further clarification of the problem.
