When using contemplate after first save < and ? change to characters/text after second save

Having a problem and can't seem to figuere out. When I edit my form in contemplate and add some php lines to call sections ( print $node.......... in a table cell for example. If I save it the first time everything is ok, however if I open the template back up and view it in source code. IT changes all the <? to characters as if it were plain text. Then If I save this it displays the php code converted to text for the symbols in the table.

I also have a similar problem where when creating a node by using a template. When I enter data for example in a CCK field as text. I look at it in my FCKeditor box and it looks ok. But when I publish it it shows the

and tags.

Not sure if both are related. But I would appreciate any help you can provide for these.

Thanks
