I had renamed and removed some files from my project. For some reason my .aspx file, named "fabalrev.aspx" won't open because it can't find "fabalrev.aspx.vb". "fabalrev.aspx.vb" which is the code-behind file is in the same directory as fabalrev.aspx as it should be. The html code of fabalrev.aspx contains the setting, Codebehind="fabalrev.aspx.vb" in the first line. How else are the .aspx and .aspx.vb files linked together??
