I've got something like this...
...for a button.Code:document.getElementById('bump23id').value= (?)
There is an input field (a text field) with the name/id "bump23id".
When someone clicks the button, I want the "bump23id" field to go up one number (like if it's already at 3, it will go to 4)
I also want to create a second button just like the first that will make it go down one number.
How do I make it get the current value of the input field and then add or subtract 1 from the number to create the new value?
