Help with integer field

[Michael Pierce]

I have an integer field in one of my collections and I am pulling the info just fine and displaying it in a label. But I cannot add the new points earned during the turn into the label with the existing score pulled from the database.

I'm not 100% sure where you want to add new points.. can you provide more details what you are trying to do?

Ya. Basically I have a layout that displays the score of the current game in a label. The score is grabbed from a field in my "game info" collection I have on my Appery DB. As the player plays their turn they accumulate new points and I want to add those new points to the existing label that is displaying the points from the database.

Hi Michael,

You can read Label text using the "text" function:
codevar currentScore = Appery("labelName").text();/code
Use it to change Label text:
codeAppery("labelName").text(currentScore + points);/code

That is what I am doing now but it isn't working. I get an "undefined" exception and then I tried to used parseFloat so I could add the two integers but I get a "NaN" exception. Would it be easier if the player score field in the database collection was a string rather than an integer?

This is my code I am using now:

var player1CurrScore = Appery('player1Score_lbl').text();
var player1NewScore = currTurnScore + player1CurrScore;
Appery('player1Score_lbl').text(player1NewScore);

I also tried:

var player1CurrScore = Appery('player1Score_lbl').text();
var player1CurrentScore = parseFloat(player1CurrScore);
var player1NewScore = currTurnScore + player1CurrentScore;
Appery('player1Score_lbl').text(player1NewScore);

I am implementing all of this in a function that is being called on a button click where everything else in the button click function is working properly. Just having issues with this one.

What text do you store in Label? IS there numbers only or you store there a text, too?
Try the following instead of the second line:
codevar player1CurrentScore = parseFloat(player1CurrScore.trim());/codeto delete spaces in the beginning and in the end of the line.

I'm still getting the NaN exception. The only thing I did was create a get_game_info service and then data mapped the value from the response to the player1Score_lbl. The current value is 0 in the database and the label displays it perfectly, but as soon as I try to update it I get the NaN exception.

It's difficult to say where the problem lies.
Probably in "player1Score_lbl" component there is a text that is not a float number.
Prabably in "currTurnScore" variable there is a string, not number.
