says clients aginvest number is invalid

May I know what the exact error message you have encountered is? Where exactly are you trying to enter this number within your client's settings?

In the meantime, please verify that the number is correct. Ensure you enter it without any spaces or dashes, as some system fields are programmed to accept it without these characters.

If you're referring to something else, please let us know. We're here to help you.
