You can only use emp no in the formula if it refers to a NAMED RANGE. As you cannot have spaces in a named range, I must conclude that you do not. This being the case, it would be easiest to create a named range. Simply select all the data you want to lookup IN on Sheet2 and follow menu path
Insert>Name>Define
Give the range a name (eg emp_no) and click ok
Once you have that, then the following should work:
=VLOOKUP(B2,emp_no,2,false)
