Passing data from main form to subform not saving data to table (1 Viewer)

Hi All.... I have a database with 3 tables ( employee, topic & training ) and 2 forms. On my Main form ( training ) I have 2 combo boxes for the user to select the employee name which is based on the employee table. I have a sub form ( training sub ) based on the training table, which is a continues form that has a combo box which is based on the topic table which they select the training coarses that they have taken. My problem is getting the employee info to save to my training table. It saves all the data except the employee info. I have tried doing a hidden field which gets the info from the main form but will not save iit to the table. Im not sure how good I explained this so I have attached a copy of it. Any help would be great as I am at a total loss.

Thanks Don
