i am writing a script to verify a application form.
for example,
my form has 3 fields: name, address, phone
3 of them are mandatory. so my test script
so i would like to have a test script can test all correct and wrong combinations like empty name,empty address ..etc
each combination gives different message.

therefore, in my datapool, I'd have some data row which has some data column missing.

the problem in playback, when it finished fill in an empty string into a form field. it just like stopping at there. it just complained empty string. it is supposed to click a submit button and display the error message in another new window.
