    Hi,

    Thanks for your help

    Unfortunately, I'm not authorised to share my project.

Sorry, I don't get it. What do you mean by "This issue can be solve from your side with this modification"?

If you are not able to share the project, then we can not do anything to help you debug the IE as each design is unique.


Best Regards,

    Hi,

    Because we can't solve this issue, I just mean that this error is not a stumbling point for me anymore.

    I can't share my project, so, I understand your inability to help me with this problem.

    Anyway, thanks for your replies,

    Best regards,
