So change or delete the comment.
can anyone advise me on how to use jumper to change the address?
What jumpers you haven't said what hardware you have!
On these chips there are three address lines, you put them to zero or one depending if you need a zero or one in the first three bits of the address.
Use an I2C scan program to see what address your device is currently sitting at. There have been a few posted over the last few months hers, google for one.
