Hi,
Its not working cause It doesnt do anything when I click the button. I got know if I want my number to go negative. I am new to this. You told me to try this i would try
if(direction=='nw'){
x = 1;
y = 1;
}
so do I change my code that I have? else if(direction== 'nw') {
x = 0 + (309 * pansize)/2.0;
y = 0 + (309 * pansize)/2.0;
I dont know what I am doing?Could you help me?
Thanks,
Albert

what happens?
you may want to check what x and y are coming out as.
often + will concatenate numbers instaed of adding.
also, are you sure you want x and y to go negative as you
have made them in 'nw' for example?
i would try
if(direction=='nw'){
x = 1;
y = 1;
}
which i think should recenter you on the upper left corner of the map.
