[amra01]

hi i want to create a test with muliple choice
so i create some option groups with a value to each answer that i store.
the problem one is that if i give the same value to 2 checkboxes of the option group then if i chose the one of them then the other "0" is selected too
what can i do?
the other problem is that i want to have some field that i will add there the sum of the fields something like the final score how can i do that?

You need to assign unique values to the options of the option group. You will need to use code to convert the choice to a value you can work with. Look up Choose() as a possible solution. You can also use IIf() or

can you give a better hint i don't have a clue...about coding...
i thought i could do a trick use an option button outside the option group but then the user can select 2 answers at the same time....

about the sum of the them? can you help me? i have a field and i want the sum of other fields.
