As far as I understand from your little explanation of the issue,I point to this question ,do you need to capture the runtime unique values and try to verify them?
if so let me know ..otherwise be eloborate your issue with appropriate statements.
OK. Sorry for not being clear. I have a Siebel application.
Here is my steps to automate:
2) Select tab, let's name it "Test"
3) Click button "Add"- A new row appears
4) Add some details to new row
5) Verify that a new row exists
