Forms :: Automatically Insert Data To Another Table By Completing Checkboxes

I'm on my way on creating a simple Database for a company. This database contains several tables, one of the tables will record information about the training that had been completed by each employee. There are about ten sections of training that should be completed.

For instance, I have two tables called 'Development' and 'CSA_Lisence'. 'Development' is the table that record the information about training which containing ten checkboxes (which represent ten sections of training) and CSA_Lisence will be automatically requeried when all of the checkboxes on Development are fully checked.

Here's the step I've been worked on :

First, I made a function called 'CheckCompletion' to ensure whether all the checkboxes are checked :

Code:
Public Function CheckCompletion() As Boolean
Dim blnComplete As Boolean
Dim strCompletionSummary As String
strCompletionSummary = Basic_Inspection & Certifying_Staff & Safety_Management_System & Regulation_Part_145 & Part_M & EWIS & Fuel_Tank_Safety_Level_2 & Dangerous_Goods & Human_Factor & Basic_Supervisory_Training

[Code] ....

Second, I made a function called 'UpdateEmployee' to handles if all boxes are checked :

Code:
Public Function UpdateEmployee()
Dim emp_numb As Long
Dim emp_name As Long
Dim strsql As String
emp_numb = [Forms]![development].[employee_number].Value

[Code] ....

Then, I put this code on every checkbox's after update event (example only) :

Code:
Private Sub Basic_Inspection_AfterUpdate()
Call UpdateEmployee
End Sub

The problem is, nothing happened with the tables. However, when I managed to remove the 'If checkCompletion' condition, it worked and the 'CSA_Lisence' is requeried, but I will have ten multiple records with same contents (I just need one record per employee). I guess there's something wrong or missed in my code. Or i need to remove something?
