GridLayout - Layout of Applet Help
Hi everyone I am in a bit of a time crunch and unsure what i am doing wrong with my applet/html page which calls it. Its a fairly simple applet with a few textboxes, checkboxes and one calculation. But when i load it, the format is all over the page, its not organized at all, i am lost. I have been at this for about a week. Can anyone please help me, code is below.
Thanks in advance
Rob
