Error The operation + cannot accept the arguments

I got problem that i cannot find solution. This might be because i'm not the person from IT background. I hope somebody could help me on this.

I try to build an app. I follow steps from someone project in utube, but i make some modification.

The error appear The operation + cannot accept the arguments: , ["Text for Label2"], [1]

From the information you gave it is not possible to tell you what is wrong, but looking at it, it seems to me that "Text for Label2" is not a number and therefore + does not like it.

Have a look at a workaround

Ok. Thanx. That is it. I've change it to 0. IT IS SOLVED
