Call a procedure with multiple parameters - Help

Hello,

I am trying to execute a procedure with two parameters on "Add page" event. I have tried with the following code on "Custom Add" event but unsuccessful. Any help would be greatly appreciated.

CustomQuery("EXEC buildPayPeriod '" .$values["CurrentYear"]. "' , '" .$values["PayPeriod"]. "' ");
return false;

I can run the procedure successfully on the SQL Management Studio(e.g. exec buildPayPeriod 2021, 'Bi-Weekly'. The procedure populate a table based on the parameters. I am getting the following error message:

Call stack
