Yes, I was thinking of doing that. However I must have the ability of being able to change the rate for any ingredient. So I'm thinking of having a SuggestedAppRate field in tblMaterials, and an AppRate field in tblIngredients, and setting the default value of AppRate to that of SuggestedAppRate, so that it can be accepted in normal circumstances, or changed in others. Oh! Wait. I think I tried something like that before, and found that I can't change the default value of a field once a field in the record has changed (in this case, the MatID). Is this right? I'm going to have a play with this. If this does happen, is there a way around it?
Thks,
Graham
