Try this:

if Request.Form("AskEdit") = "Edit" then
    response.Redirect("edit_category.asp?fid=" & request.form("fileId1"))
end if

If the code that you have posted is a direct copy of your code, you have a . where there should be a " which may be preventing the value from posting correctly.

<input type="hidden" name="fileId1" value=.<%=mid(FileName.Path,instrrev(FileName.Path,"\")+1)%>"> 

should be

<input type="hidden" name="fileId1" value="<%=mid(FileName.Path,instrrev(FileName.Path,"\")+1)%>">

The answer is simpler. You have to put call when calling a method using parenthesis. Or not use parenthesis.

call response.Redirect("edit_category.asp?fid=" & request.form("fileId1"))

or

response.Redirect "edit_category.asp?fid=" & request.form("fileId1")
