Error message when merging two tables

Hi,

 

I would like to merge two tables but when doing the merging.

An error message shows up : "we were unable to determine how many matches the selection will return"

I've tried to change in the same formate ( text formate) but it does not work.

Once i click on OK, the error message showing index was outside the bounds of the array.

Could anyone help me with this issue ? 

 

Thank you.

 

Best regards,

Amy
