How does one declare a variable to be global to all forms in a project? Tried declaring variable at project level, not using a ‘var’ (using JS) to no avail. Ideas?

var myGlobal = 'some string'; ... the rest of the code for your project
Note that polluting the global namespace is generally frowned on.
