Question

Dynamic Table Row Add - javascript onChange event does not work in IE

Asked by: inickinfosystems

The following basic script works fine in firefox by not in IE. Can anyone
spot the problem? In IE I can only delete the first line but not the lines
created by javascript. Also, look at the HTML code for the first line
(click the Table HTML button:)) you will fine that the code displayed is not
the same as
was written. "onChange" was changed to "onchange" etc. Please help.
