Multiple addFoundSetFilterParam Help Please!

Hi ,
I am using following to permently filter records on a tabpanel and it is working fine, however I need to add a ‘AND’ statement to refine the current set filter.
I have read that you can have a multiple ‘addFoundSetFilterParam’ but am unsure how to inplement?

controller.addFoundSetFilterParam('quote_text', '=', 'SALES ORDER PLACED')
controller.loadAllRecords()

AND restrictions are easy: just add another filterParam like this

controller.addFoundSetFilterParam('quote_text', '=', 'SALES ORDER PLACED')
controller.addFoundSetFilterParam('quote_text', '=', 'ANOTHERVALUE')
controller.loadAllRecords()

Thanks Patrick,

That did the job
