Control Insert with ToolTip

[Jason]

IHello,

I am trying to insert a preslected set of values into a table (Activity)  trough the check box list. however I am getting nothing inserted. I have got 3 tables which are.     Job,      |        Activity,                |  ActivityDetails
                                            ========================================
                                                              |        JobId                   |
                                                              |       ActivityDetailIdI     |

the preselected values are coming from the ActivityDetails table (5 values).

I am folling the example from the demo." Control Insert with ToolTip"
