how could I solve this equation, any idea? - imacros

Question

I have the code for imacros
I would like to receive the result.
TAG POS=1 TYPE=INPUT:HIDDEN ATTR=TYPE:text&&NAME:firstNumber&&VALUE:8
TAG POS=1 TYPE=INPUT:HIDDEN ATTR=TYPE:text&&NAME:secondNumber&&VALUE:9
SET !EXTRACT_TEST_POPUP NO
SET !EXTRACT NULL
TAG POS=1 TYPE=INPUT:HIDDEN ATTR=TYPE:text&&NAME:firstNumber&&VALUE:8 EXTRACT=TXT
SET !VAR1 {{!EXTRACT}}
SET !EXTRACT_TEST_POPUP NO
SET !EXTRACT NULL
TAG POS=1 TYPE=INPUT:HIDDEN ATTR=TYPE:text&&NAME:secondNumber&&VALUE:9 EXTRACT=TXT
SET !VAR2 {{!EXTRACT}}
SET !VAR3 EVAL("var a=\"{{!VAR1}}\"; var b=\"{{!VAR2}}\"; var z = (((a + b))); z")
PROMPT {{!VAR3}}
I already tried this code, and even result
click to see the result of imcros
any idea how I can solve.

Answer 1

All what you need is to parse the variable to int before plus action.
var a = parseInt( "{{!VAR1}}" );
var b = parseInt( "{{!VAR2}}" );
var z = a + b;
z;
So for your source code you just need to do:
TAG POS=1 TYPE=INPUT:HIDDEN ATTR=TYPE:text&&NAME:firstNumber&&VALUE:8
TAG POS=1 TYPE=INPUT:HIDDEN ATTR=TYPE:text&&NAME:secondNumber&&VALUE:9
SET !EXTRACT_TEST_POPUP NO
SET !EXTRACT NULL
TAG POS=1 TYPE=INPUT:HIDDEN ATTR=TYPE:text&&NAME:firstNumber&&VALUE:8 EXTRACT=TXT
SET !VAR1 {{!EXTRACT}}
SET !EXTRACT_TEST_POPUP NO
SET !EXTRACT NULL
TAG POS=1 TYPE=INPUT:HIDDEN ATTR=TYPE:text&&NAME:secondNumber&&VALUE:9 EXTRACT=TXT
SET !VAR2 {{!EXTRACT}}
SET !VAR3 EVAL("var a = parseInt( "{{!VAR1}}" );var b = parseInt( "{{!VAR2}}" );var z = a + b;z")
PROMPT {{!VAR3}}
