// This is the call URL. It will always require the method being used to be sent in the URL
// Depending on your setup, you may need to adjust the path to this url
// For example: /your/path/to/phph1/phph1_call.php?method=hmyv2_getLastCrossLinks
var url = "phph1_call.php?method=hmyv2_getLastCrossLinks";

// The formdata variable is always set
// Even if there is no form data we need the dorequest sent
var formdata = "dorequest=1";

// Run the getPHPH1Data function
getPHPH1Data(url, formdata);
