main form is the customers information
the subform has all the repairs in a list I want to be able to open the repairs form so I can enter more information in it or get to it quicker. the sub form only has limited information in it
I don't understand. Why can't you add more information into the subform? Do you want to open up a popup form of some kind with linked information? Does the subform have more fields but just not displayed? If you open the repairs by itself and not have it linked you customer data will not be in sync.
I could but it would make the subform very big at the minute it just has the id then it has daten entered time entered type and when it was fixed and what the problem was now I want to add in another form what I did to fix it any parts I used and calculate the cost of the repair who fixed it when it was fixed and all this is too mush for a sub form
