I have forms which are evaluated by different code depending on which submit button is selected by the user. When using <input type="submit" name="submit_button_name" ...> it has been simple to determine which button was clicked. In my ASP code (VBScript) I've used:<BR>"<% if NOT isempty(Request.Form("submit_button_name")) then ... %>"<BR>But I would like to use <input type="image" ...> for the buttons. Unfortunately neither isempty nor isnull appears to evalutate for the button name. Does anyone have a suggestion on how to determine which button was used to submit the form when using an image?
