There is an app has Text fields "revenue_text"(content is "223") and "cost_text"(content is "100"),I would like to get profit in a calculation field by code below:

but ,there are error messages :
1."the result is not a valid number "
2."invalid value 123.0（number）:must be string"

what's wrong with it ?

My purpose is to get string from text field ,then turn it into number in calculation field .
It seems the calculation field is text type instead of number type which is wanted by me .
How can I make it ?

The script as follows:

var a=@revenue_text ;

var b=@cost_text;

var c= parseFloat(a);
var d= parseFloat(b)
var profit=c-d;
profit;

  It is very important that I use the feature to achieve a little bit complex function to handle orders and invoices .I hope we can make it done .

  Once a calculation field has been created its return type is locked. In your case it looks like you have created a calculation field that returns a string and now you're trying to return a number.

  Remove your current calculation field and create a new one that returns a number from the start.

  Hi ,
  I met the same situation as your instruction .That means it worked in some calculation fields ,but some fields don't work .
  please refer the screen shot :https://drive.google.com/file/d/0B3JEgK0GXrSSZ205Q2J4Wjl2clk/edit?usp=sharing

  I am not sure if it's the result from function :"parseFloat" ? but it does work in my previous fields.

  You are probably ending up with NaN as a value for sum at some point or for some items.

  I'm sure "ar[i]" in the pic is a number("1","2" or "3")(not NaN), and this code works well under node.js, Can you tell me why it shows "the result is not a valid number"?

  The issue seems result from the semicolon in the end . When I deleted the semicolon ,just :"sum",instead of :"sum;",It works and shows the right sum result.

  I've not been able to solve the issue. And yes, I'm sure the calculation field is a numbers field, since when I remove the string and the parsing everything works fine again.

  Here's a screenshot: https://www.dropbox.com/s/54lz50j62taregu/Screenshot%202015-01-16%2022.55.14.png?dl=0

  Did you try to add a semicolon ";" or a space " "at end ? That it "Number " or "Number;",or "Number; " or "Number ;"

  杜晓闻, I've tried all four possible combinations from blank space and semicolon. Always the same result.

  I checked my notes :It was number field and all right when it's "profit;"in the last line ,but later (maybe a few days later ),it showed "the result is not a valid number", then I tried a lot ,but it only worked as "profit" (deleted the semicolon ).
  good luck
