Customer Records Data Sheet

i use excel in my dispatch office. i am working on a new workbook and could use some help. In one sheet of the workbook we enter in customer calls. i would like to keep customer records in another sheet, which would include their address, phone numbers, and past invoice numbers all on the same row of the customer database sheet. At the top of the sheet that we enter caller information i would have a table set up to automatically fill in the customer info based on the name typed in,

if the customer exists in the customer database sheet of the same workbook the table will automatically fill in their address, phone number and past invoice numbers. i was thinking something like this =IF(COUNTIF('Customer Database'!A:A,Blanks!D6)>0,'Customer Database'!A2,"Not Found") ....the problem is that no matter who's name i enter, it will always add the information from row 2 of the customer database sheet. i need it to take information from the corresponding row(if customer name is found on row 45 then my formula needs to enter the info from row 45, not row 2. not sure how to do this.
