check boxes auto fill after submit--Help

[krazyspur]

Hi, I'm fairly new to Javascript. I have a problem. When I click on the Get Quote button at the bottom of my code, after the validation alert boxes, the check boxes automatically fill. I don't want this to happen. Any help would be greatly appreciated. Thanks in advance.

I have attached my code.

Check your '=' signs.
A single '=' sign assigns a value ( item=value; item is set to value);
Double '==' compares values (item==value; item is equal to value)
