First off thank you in advance for any and all help that you can give me.. What I'm trying to do is to use an array for a mortgage calculator that displays the months payment for 3 different loans without it scrolling off the screen. When I compile it I get the following error
"(C:\Documents and Settings\new one\Desktop\POS407\MacApplet46.java:18: '(' expected
{
^
C:\Documents and Settings\new one\Desktop\POS407\MacApplet46.java:118: '}' expected
^
2 errors
Tool completed with exit code 1"
for the life of me I can't figure out where I went wrong. I believe it should work the way I have it set up or am I completely wrong?
