In Access, the Choose function selects and returns a value from a list of arguments based on a given position.
The syntax for the Choose function is:
Choose(index, choice-1[,choice-2, … [, choice-n]] )
You can use Choose to look up a value in a list of possibilities. If index is 1, Choose returns the first choice in the list; if index is 2, it returns the second choice, and so on. The Choose function returns a Null if index is less than 1 or greater than the number of choices listed.
index is position number in the list of values to return.
choice is variant expression containing one of the possible choices.
This example uses the Choose function to display a fruits name in response to an index. Now the MyChoice variable would contain the value “Orange”.
You can also use the Choose function in a query.
