you probably want to create your array outside of the click event.

also outside the button click event, you probably want to create an integer variable which represents the current value.

after you have those in place, you will increrment the integer variable inside the click event.

you may want to put some extra logic inside the click even which makes sure the integer value does not exceed the total amount of elements in the array.

this is just logic, .. sorry i don't code vb that well.

good luck.
