How to transfer calculated value into table field

[Guest]

I have a calulated value using VB code called num this number needs to be
put directly into a table called ID num. What is the VB code to do this?
I am not really sure on the format how to reference a table to put the value
that I calculated to put it into the field.

If you are updating the value of an existing record ...

Dim strSQL As String
strSQL = "UPDATE YourTableNameHere SET YourFieldNameHere = " & _
YourVariableNameHere & _
" WHERE " & _
criteria that selects the correct record to be updated here
CurrentDb.Execute strSQL

If you're adding a new record, change the SQL statement as follows ...

strSQL = "INSERT INTO YourTableNameHere (YourFieldNameHere) Values (" &
YourVariableNameHere & ")"

Hereis what I did with my table names and values. The table I want to put it
in is called Genetic ID num. The value that I want inserted is RandomNum
into geneticIDnum.
It is giving me a compile error right here "WHERE"

Also what do you mean by criteria that selects the correct record to be
updated.
Do I even have to put the WHERE in if I am not going to update anything I am
just going to put the RandomNum into that field?

strSQL = "INSERT INTO Table: Genetic ID num (geneticIDnum) Values (" &
RandomNum & ")" " WHERE " & _
criteria that selects the correct record to be updated here
