You have an input box with a presetted value?
(like a field "name" and the value "type your name here")
Start recording your script.
Fill in a value into the field.
Go to the relevant step in QA Wizard.
Select the Option Type (Popup) and look for "value".
You see the value, you entered before. Now you can change the value or use a variable instead of a static value.
Hope it helps you!
