In a perspective design, I have a pump where I am writing a script in pump "onClick" event. I expect the script will change the state of the pump to "running" in both UI and the tag property. When I run the project in browser, it shows "Error\_Configuration".

In 1\_Screenshot file it shows the configuration and in 2\_Screenshot shows the error. Any idea what is the issue here.

Note that there is no tag associated with the pump that change the state, I am expecting that on every click on the pump, it changes the state to running (property of the pump) and then when the tank goes to 100% (which comes from integer tag used for counter to reach 100%) the pump stopped.

Hi @Anirban-Debnath,

Your issue is that you cannot bind a property with him self.

I would rather use a custom property that you set when clicking on the pump object and reset then tank value is above 100%

Then you link that custom value to your pump state

regards

Hi @Anirban-Debnath,  
here and export of my test view.

 ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/3/0/30fe54bce1fe3cddad7dea54270d674b97f3cf45.png)  
Under the custom properties of the view you have the tankLevel and the pumpState.  
Those are linked to the pump object and tank object. on each you have also a onchange script you can check it by right-click on the property and edit on change script.  
there is an on click script on the pump to set the running status.

Regards
