When you get an error in Review Loan Products tab that says “Total loan amount ($$$) is different of total loan amount ($$$) on funding worksheet. Please correct the difference.”, all the tabs from Compare Loan Products up to Lodgement are going to be greyed out.
This means that the loan amount in Funding Worksheet and loan amount in Review loan products are not the same.
You can correct this by going to the Funding Worksheet tab and entering the same loan amount as in the Review loan products tab.
When loan amounts are the same, the error will be gone, tabs will be unlocked and you will be able to proceed with your application.
