When you specify windowtype, the window object specified in windowtype must be the same data type as sheetrefvar (a data type includes data types inherited from it). The data type of sheetrefvar is usually window, from which all windows are inherited, but it can be any ancestor of windowtype. If it is not the same type, an execution error will occur.

PowerBuilder doesn't automatically copy objects that are dynamically referenced (through string variables) into your executable . To include the window object specified in windowtype in your application, list it in the resource (PBR) file that you use when you build the executable.
