Error evaluating UI Expression

Question

i AM WORKING ON THE BUILDING A PORTAL FOR THE APPIAN DEVELOPER COURSE AND I WAS AT THE PART WERE I WAS SUPPOSED TO RIGHT CLICK ON TECHNICIAN TASK AND CLICK VIEW FORM. 
 WHEN I DO THAT, I GET THIS ERROR! CONFUSED AS TO WHAT TO DO. 
 
 THIS IS THE EXPRESSION FROM WHAT I BELIEVE IT IS TALKING ABOUT! AND I HAVE NO IDEA WHAT IT IS TALKING ABOUT! 
 
 THANK YOU

Hello paigeh2103 The value of riloutage[W2286WPO Power Outage.status] is " reported ", but it should be " Reported " to match the constant cons!W2286WPO. Appian treats choice values and dropdown values as case-sensitive. Check below code for better understanding. a!localVariables(
 local!value:"reported",
 /*If you change "reported" to "Reported" to match choice value it will work*/
 a!dropdownField(
 choiceLabels: {"Reported","In Progress","Fixed"},
 choiceValues: {"Reported","In Progress","Fixed"},
 label: "Dropdown",
 labelPosition: "ABOVE",
 placeholder: "--- Select a Value ---",
 value: local!value,
 saveInto: local!value,
 searchDisplay: "AUTO",
 validations: {}
