I'm pretty new to ignition.

Looking to use an onClick event to write a value to a tag using a push button. Does the script below look correct or is there something that i'm missing. Thanks in Advance!

def runAction(self, event):

```
										 params = {
												 'deviceTagPath':[RiversideWTPProvider]HighService/HSP No1 Check Valve/OPEN,
												 'valueToWrite':1,}

```

I see the creation of a `params` dictionary and nothing else. So the dictionary will be created, then discarded at the end of the script. Your script should look more like:

```auto
	system.tag.writeBlocking(['[RiversideWTPProvider]HighService/HSP No1 Check Valve/OPEN'], [1])

```

Note the placement of the tag path in a string, and both tagpath and value placed inside square brackets to make one-element lists of each. (See the docs for `writeBlocking` for why that is.)

Also, you should not use click events on buttons, as they don't respect the button's enabled/disabled state. Use the `actionPerformed` event instead.
