Okay, those are errors but not the heart of the issue. If you use Layers, you can see that the repeater has a container (as usual) and within the container are #inputBox and #displayBox. Theses two boxes (and their contents) are the ones that won’t display properly unless I do the hide/show or show/hide code ala your example. By default, the #displayBox is shown and the #inputBox is hidden when the page loads. When the user clicks the #editIcon, then the #displayBox should be hidden and the #inputBox should be shown. If the user hits either the #saveIcon or the #cancelIcon, then the reverse happens. Sorry I did not make this clearer.
You can use me as the test member – this will not confuse anyone.
