Deletion of a data in Sub Form to update a control in main form

[cheer]

I have a main form call frmARSystem. On top of this form, there is one text box [txtPrice] and one sub form [subForm_ARSystem]

When user press the delete KEY and remove one row of data in the subForm_ARSystem, I want the txtPrice on the main form ARSystem to be updated accordingly.

I have tried the following but it doesn't work :-
1) Having the event "AfterUpdate" at both the main and subform
2) Having the event "Dirty" at both the main and subform

The method I have used to refresh the main form is REQUERY. No syntax error is detected and the only thing is the txtPrice is not updated after deletion is done.
