Hey guys, im new to java and am wanting to disable a button say "20" if they do not have enough funds in their bank. I have had a shot at it but i keep getting "operator cannot be applied to java.lang.string,double. I'm pretty sure im missing something simple here.. =(
Yes, the simple thing you missed was to tell us which of those 400 lines of code produced that error message. I wouldn't expect anybody to examine the whole lot carefully to figure that out, when you could just tell us.
