Importing data from excel into Relational field of a Table

Hi!!
I am new to BD and still trying to digest bits and pieces of it.

I have two tables

Table Name/ Field Name
1. Employee Table -

- a) Emp ID - Number
- b) Emp Name - Text

2. Employee Punch

- a) Emp ID - Number -- Related field
- b) Date - Date
- c) Time - Time

I want to import punches from excel consisting of Emp ID, Date and Time Columns in to "Employee Punch" Table, I am able to import Date and Time but not Employee ID Column


Need Help

Thanks in Advance
