Here is the scrip that I put on the button background color: export function Button_4_BackColor_Trigger(item, triggerDataSet) { var value; if (Tags("Errors_number") > 0) { Screen.Items('Button_4').BackColor = 0xFFFF0000; GraphicView.PropertyFlashing("BackColor", true); } else if (Tags("Alarms_number") > 0) { Screen.Items('Button_4').BackColor = 0xFFFF9900; GraphicView.PropertyFlashing("BackColor", true); } else if (Tags("Warnings_number") > 0) { Screen.Items('Button_4').BackColor = 0xFFFFFF99; GraphicView.PropertyFlashing("BackColor", true); } else if (Tags("Operator_messages_number") > 0) { Screen.Items('Button_4').BackColor = 0xFF99CCFF; GraphicView.PropertyFlashing("BackColor", true); } else { Screen.Items('Button_4').BackColor = 0xFFCDD3D7; GraphicView.PropertyFlashing("BackColor", false); } return value; } Does anybody sees what is wrong with the script because it is not working at all, nothing is heppening?

This will also crash in your script. You can also use RTIL Trace Viewer for analysis: https://support.industry.siemens.com/cs/de/en/view/109777593 Also here are some basic tips for your programming: https://support.industry.siemens.com/cs/de/en/view/109758536 Bye Murof
