Search based on Subform Value

[TJunior]

Hello There,

I am currently in the process of developing an ADP and have a problem that I cannot seem to resolve.
I have a main form which has an embedded subform. I would like to be able to double click on any perticular row on the subform (datasheet view) and in turn have the search open a seperate form based on a match. I have been looking and cannot find the controls of a subform to allow me to do this.

I would be very gratefuol for any help on this

Thanks
