OT: Javascript help?

[Gene Dascher]

How are you passing in the field info to the function?

You should be passing it in like

stripBadchs(document.MyForm.MyField, "letters");

without quotes around the form field object string.  If you have to use
quotes or have to build the form field name string to pass in to the
function, then add this to the beginning of the stripBadchs function:

var	idObj;
idObj = eval(id);

then use idObj throughout that function instead of id.  Otherwise, using the
following:

 	alert(id.value);

	should display what you want.
