Hi, I have a suitelet and im trying to add a function to a button, looking through the docs I found the function clientScriptModulePath I set it to the client script but, how do I use the functions that are on the client script, because Im setting the button like this

form.addButton({ id : 'custpage_excel', label : 'Test', functionName : 'test()' });

and before that line is

form.clientScriptModulePath = 'SuiteScripts/SLP Accounts payable recd not vouchered/STEMCO_CUE_recNotVouchClientFunctions.js';

but that did not seem to work
