Hello,
I have read your specification for this project and am fully capable of completing this project for you. I spent all of this past year doing various projects in Microsoft Access. Several projects involved creating access databases, and then creating protocols to fill them, so a simple updating procedure won't be difficult for me to implement. Your spec sheet was very clear on your needs, so I can't wait to get started on your project!
I do have one question. Why do you want a button to update T_ref_Pay when it could be done automatically? I expect that it might make more sense once I see and understand your database system better, but at a first glance, it seems that it would make a better experience for you if it were to update T_ref_Pay automatically from the T_time_emp_id data. I have no problems writing it either way, but I am curious as to why you requested a button.
In any case, I would love to talk to you about this project, and any other potential projects you have in mind, so feel free to message whenever you get a chance! I look forward to working with you!
Thanks,
Harrison
