I am very sorry to say that your guidelines are teaching us like a random shooting. there is no straight forward procedure. Just saying this and that will do. But a practical solution to show a webform on my default basic page. if simply O converted the Text Format into PHP code and paste some module code, It is landing me on error messages mine.
There must be a step by step leading, right, Am I need to generate any element to connect the webform module and How I need to pass the fields as arguments. Without giving any constructive mechanism to do all these things, How could you dump all these modules on our faces?
I know PHP code very well, but what is the use, I am unable to show a form of just two text fields and one button by these modules!? Ten days have passed after installing the drupal package.Nothing I could display there on my Home page. There must be a node which can access to a module by giving the module name as argument. By passing secondary arguments as fields and we can get a way to build a form. but nothing is constructive and descriptive here. Every thing is vague sugestion lists.
