Coding help Access

In access I have this form where I disabled the navigation/search bar. I did this because the only way I want some one to go to another entry in the form is to search for it. So I created a text box and button in the header. This is for an Inventory database, and I'm searching for the Tag_ID. I was wondering how I would go about coding the button, or is there a simpler way of doing it.
