Im new to Angular and Im trying to find out where Im going wrong with this and why Im getting this error.

Can't resolve all parameters for TemlComponent: (?). at syntaxError (compiler.js:1016).

I have created a working example here https://stackblitz.com/edit/angular-w8jyjs with all the pertinent files.

The code probably contains several redundant items and methods that I created while attempting to fix this. removing a;ll parameters from the constructor in teml.component.ts gets rid of the error.

Guidance to what i've done wrong here would be appreciated.

The constructor property in Angular is meant for defining dependencies for the initialisation of your component and not for declaring a property, which explains why you're getting the error.

Consider using an @Input() instead.

Here's an updated demo.

So this was entirely a result of my inexperience and trying to apply examples without full knowledge. I appreciate the feedback and quick answer. I was trying to use the constuctor to pass a parameter which is not the correct way in Typescript.
