    Hi @Lori Carenzo

    It sounds like you're receiving an error when trying to Save a sheet.

    In this instance, I would recommend creating a case with Smartsheet Support showing full screen captures and/or a screen recording of your issue, including the steps you took leading up to the message and the sheet URL.

    Hi @Lori Carenzo

    I checked in with our Support team and they have not received a case from you yet in regards to this issue.

    If it's still occurring, please open a new Support Case from the Portal Home Page,

    and provide the following details in the Description box: 

    • Screen recording of when you receive the error message
    • Sheet URL that you receive the message
    • Does the same error occur on any other sheets?
    • Does the same error occur if you create a copy of the sheet with Save as New?
    • Are any other Shared Users seeing the same message, or is it just yourself?
    • What browser are you using, and do you see the same error on other browsers?

    They'll be able to troubleshoot this with you in a private channel where you can share these details!
