There are many ways to set up the form. Inside the form itself you can do any normal HTML, so the form can take on any look. Checkbox Creates a small box the user can check or uncheck. Note the user sees nothing, but it is there. Radio Creates small option circles where only one of a type can be picked.
Text Creates a small text box the user types in.
Submit Creates a standard command button which submits the form info to the script. Reset Creates a standard command button that resets the form. Image Uses an image as the submit button, so you can customize its look. Another input you can use is the selection list. This is the default text since I typed it here.
