As we have seen in numerous examples, to call a function simply use the function name followed by parentheses containing the arguments, if any:
FunctionName(p1,p2,...,pn)A function defined in a survey's script node may be called in all script contexts; from other script nodes, conditions, response piping (within ^s) and in code masks and column masks in the same survey.
Note: When calling a function, ensure that you always include the parentheses and any required arguments. Calling a function without parentheses causes the text of the function to be returned instead of the results of the function.
