System Architect Mission US-2009 Acceptance criteria ERROR Source— Invalid expression or reference: error

[GerdaV98 (Gerda Varazinskaite)]

Hi,

I am on the mission exercise of system architect and on the step “US-2009: Display customer information to confirm authentication”. I am getting an error on Data Transform Property Source syntax:
D_CustomerCredentialLookup[UserName:.UserName,Password:.Password].pxResults(1).pyGUID

Error message:

Source—

Invalid expression or reference: error: Declare-Page ‘D_CustomerCredentialLookup’ does not take parameter ‘UserName’

The system does not allow me to save newly created property “SetCustomerKey” because of the source error.
All steps are performed correctly,a ccording to guidance and walkthrough.

Would appreciate your help

Thank you
