Hi Anitha Dharmalingam ,
In the given code, I noticed that the local variables you created are not wrapped inside the localVariable() function. Additionally, the local variable: salesReps contains null values, which is causing an error. Please add proper null handling and check this after making the changes.

Can take reference from this code: a!localVariables(
 /*----- reject function will remove null values from the list ----------*/
local!salesReps:reject(fn!isnull,{"A","B","C",null}),
local!repChoice:{union(local!salesReps,local!salesReps)},
local!salesRepName: if(a!isNullOrEmpty(local!repChoice),"None","All reps"),

a!multipleDropdownField(
 label:"Sales rep name",
 choiceLabels: if(a!isNullOrEmpty(local!repChoice),
 {"No reps"},
 {"All reps",local!repChoice},
 ),
 choiceValues: if(a!isNullOrEmpty(local!repChoice),
 {"None"},
 {"All reps",local!repChoice},
 ),
 value:local!salesRepName,
 saveInto: local!salesRepName
)
)
