Checkbox doesn't update in subform (1 Viewer)

[Steven]

Hi all,

I have a subform with Unbound CHECKboxes. When clicking them my table is updated correct.
The problem is that when I open the subform the next time for the NR on the head form, all my CHeck boxes are set to FALSE, but I want them to have the value that is stored in the table.
So I thought I do the following:
===========================
If PROJNR_SK <> Null Then
MR_11 = DLookup("ActiviteitJN", "Activiteitenlijst", "ACTNR_SK = 3001 And PROJNR_SK = " & Me!PROJNR_SK)
If MR_11 = True Then
Selectievakje31 = True
End If
End If
===========================
The PROJECT_NR gives me the correct number and the lookup gives me TRUE, but in my form the checkbox "Selectievakje31" still displays FALSE.
What am I doing wrong.

Thx in advance for your time and help,
Steven.

Hi John,

Thx for your reply, but this is not what I am looking for.
I just need the code to give the checkbox the value TRUE, so that it is checked, if the lookup gets the value TRUE out the table.

There are loads of people having troubles with this, but I can't find the answer.
Maybe anyone has the right solution.

Greetings,
Steven.

Try: -

If Not IsNull(PROJNR_SK) Then
