Dreamweaver from becoming unstable, it can hinder development, especially when you need to
find one small syntax error in multiple lines of code.
If your translator fails, one effective debugging method is to turn the translator into a command,
as described in the following steps:

return new Array( "OK","translateMarkup(dreamweaver.¬
getDocumentPath('document'), dreamweaver.getSiteRoot(), ¬
dreamweaver.getDocumentDOM().documentElement.outerHTML); ¬
window.close()", "Cancel", "window.close()");
}
At the end of the

dreamweaver.getDocumentDOM().documentElement.outerHTML =
whateverTheReturnValueIs
// return theCode;
dreamweaver.getDocumentDOM().documentElement.outerHTML = ¬
theCode;
}
/* end of translateMarkup() */
In the
of the document, add the following form with no text boxes:

If no error message appears and translation still fails, you probably have a logic error in
your code.

variables and properties at different points:
for (var i=0; i< foo.length; i++){
alert("we're at the top of foo.length array, and the value ¬
of i is " + i);
/* rest of loop */
}
After adding in the
