>What I don't understand is how do you go from bit to number that will be stored in the field. For example, say only the 1st option box is selected. Does it mean that the value of 1 is set to the field? And if Option 1 and 2 are selected, the value of 3 is set to the field? And in case of all three options boxes, the value is 7?
The options have numerical values 1, 2, and 4 assigned (for more than 3 options, use additional powers of 2: 8, 16, etc.). If one bit is set, add the values of the individual bits, e.g. 101(binary) = 4 + 1. To get the combined value:
CombinedValue = iif(CheckBox0.Value, 1, 0) + iif(CheckBox1.Value, 2, 0) + iif(CheckBox2.Value, 4, 0)
* (Assuming you changed the checkbox to a logical type. Otherwise, use iif(CheckBox.Value = 1...))
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
