Pull Data From Sheet Based On Criteria - Populate UserForm And Ask For Missing Data

I have a spreadsheet that is updated weekly -- but every week new info is added that needs a user to input corresponding info. I use a vlookup function to link to another spreadsheet that populates the info from previous weeks and the info that is missing shows up as #N/A...

First I was using a msgbox function to get the info:

HTML Code: 

For Each b In myrange
If Application.IsNA(b.Value) Then
Employee = b.Offset(0, -2).Value
SSID = InputBox("Please enter ID# for " & Employee & " :", "New Employee Found")
b.Value = SSID
End If
Next b

But it can be up to 30 different new employees... and that is time consuming.

I would like to make it more user friendly by creating ONE userform that displays all of the employees as labels -- has a text box in which to put the ID # -- and then has a drop down box to choose the type of employee (2 options). I want all of that info to go back to the reference spreadsheet so it will be saved for following weeks, and then redo the vlookup to get the info into the new weekly spreadsheet (I can do that part)....

HTML Code: 

Private Sub CloseButton_Click()
Unload UserForm1
End Sub

Private Sub ComboBox1_Change()
