Let's say a field values has a parameter in it. {1}

Now I want to pass a property value as param at run time and get the localized value for that field value.

@(Pega-RULES:Utilities).getLocalizedText("FieldValueName","pyCaption",tools)

I have a few properties in workpage which i will pass as param based on condition.

How get localized values for a field value when field values has parameters in it using getLocalizedText function?
