Ionic 3 Basics?!?

Edit Subject

Hi,

I am new to Ionic 3 so apologise for the stupid question :)

I have a [Server Code] script to write an entry to database but can't work out how to invoke it and pass variables fusing Ionic 3.

From the snippet (or dragging the Server Code service into the function) I get...

--------------->

this.createWorkout.execute({ // change 'createWorkout' to actual variable name
data: {},
params: {},
headers: {}
}).subscribe(
(res: any) => {
console.log(res);
},
(err: any) => {
console.log(err)
}
)

--------------->

1. I am not sure what is means with the comment "change 'createWorkout' to actual variable name".

2. When run I get a TypeScript Error stating "Property 'CreateWorkout' does not exist on type 'Screen2'" .

I have no idea where to turn with this one :(.

Any sample code based on the above would be massively appreciated.

Regards,

Ryan.
