Hi, I’m creating with Access 2010 a toolbox to help doing engineers projects. The toolbox let the user create loops with elements and his specifications (e.g.: transmitter + PLC + Relay + Junction box)[Each element has his own table with his own specifications]. After creating the loops, when I want to show the loops created I have some problems.

-)The first problem is, that if the loop don’t have all the possible elements Access shows a message box telling there is a problem finding the missing elements.(It is not mandatory for a loop to have all the elements, E.G.: Loop1= Transmitter + PLC + Relay [In this case the program will tell me it doesn’t find the Junction Box, the isolator and the rest of the missing elements])

-)Also it is suppose that only by choosing the loop you want to see, all the fields should be filled automatically. But it doesn’t work at all like this.

(From each element table there is a field with his ID, and also a field called “LoopID” related with another table called “LoopID” where I write the loop names. All this IDs (elements ID + loop ID) go later to a table called “ElementsID” where it is show like this the composition of the loop [LoopID | Element1ID | Element2ID |….].

I let my program here. The form where I want to see the created loops is called “ShowLoops”, and from the Table “ElementsID”, is from where I take the elements ID of each element table. I think my problem is in the relation between tables but I’m not sure I try a lot of things but I’m stuck and I can’t find the problem.
