I am using a VLOOKUP formula in a sheet that is used for Employee Data Entry.
I have used it so that I do not have to enter the Employer and Trade once I
pick an employee from a drop down box.

The formula works when I have selected an employee from the list but when
the cell (say I2) the formula in cell J2 & K2 show up as #N/A until I have
selected an employee.

I need this not to show up becuase it is stuffing up the rest of my formulas
and calculations for the wages.

The formula that I have used is :
=VLOOKUP(I8,'Employee''s'!$B$2:$J$999,2,FALSE)
So the way the I worked it is if I8 equals anything in B2:J999 it shows the
value in row 2 of my employee table on the Employee worksheet but it shows
the #N/A if anything I8 is blank.
