IRIS VAT Filer- SCRIPT ERROR, Line 37/25 Char: 5 Unable to get property signature of undefined/null ref

You get a SCRIPT ERROR (or similar) when trying to access the HMRC system to sign in with your HMRC or ASA login or when trying to submit a VAT to HMRC or when needing access to HMRC to make an action. This also applies if you try and login to the HMRC – read this KB

These can be linked to a issue with HMRC and the Browser you are using (normally its EDGE/Internet Explorer as HMRC will by default use these two browsers)

1) Click YES to all these pop ups and see if it allows you to finish your actions – if it dosnt work and blocks any further action, continue reading this KB. Users have reported that have clicked yes, have got it to work.

2) Help and About and check your IRIS version is up to date (older versions may not operate fully with the HMRC systems)

3) Update your PC Browser version (we cannot advise further as each Browser product settings has their design on how to update etc – for example update your EDGE/Internet Explorer)

4) Try working on another pc/workstation to access the login or submit the VAT etc as it could be a issue on that one pc/workstation. Also try another IRIS login, ask another user to try as well.

5) Try again later – next day etc.
