javascript - Simple Google Script not working -

-

i have decided use google scripts when can when using spreadsheets, start increasing knowledge. untrained , got stuck quite quickly.

i saw code on youtube different script thought extracted needed , work...

     function y_add_up_function() {       var ss = spreadsheetapp.getactivespreadsheet();       var sheet = ss.getsheets()[0];       var range = sheet.getrange["i2:j15"];       var data = range.getvalues();       var sum = 0;
    (var = 0; < 14; ++i)   {     var row = data[i];     if(row[1] == "y")     {       sum = sum + row[0];     }   }   return sum; }

https://spreadsheets.google.com/ccc?key=0auzrl_i_w9e0den2ve9ztly1u0c4n0m3rm1ozkncale&hl=en&authkey=cmrboy4e

there spreadsheet can see trying ss add have ticked y next price getting error reads:

typeerror: cannot call method "getvalues" of undefined. (line 5)

please teach me doing wrong ^_^!!!

cheers!

the error means trying call method on undefined object. if @ code, have range.getvalues(). means range undefined. therefore need @ assignment of range: var range = sheet.getrange["i2:j15"]. , here problem, getrange method , need called parenthesis, getrange("i2:j15").

here working code:

function y_add_up_function() {   var ss = spreadsheetapp.getactivespreadsheet();   var sheet = ss.getsheets()[0];   var range = sheet.getrange("i2:j15"); // <-- fix here   var data = range.getvalues();   var sum = 0;      (var = 0; < 14; ++i)   {     var row = data[i];     if(row[1] == "y")     {       sum = sum + parsefloat(row[0].substring(2)); // <-- fix floats "£ <number>"     }   }   return sum; }

also note since have pound signs in cost column, need strip signs number. here have used .substring(2), not fail safe. if e.g. forget put "£ " in cell number read incorrectly. recommend putting pound sign in column header or use more sophisticated method remove when parsing numbers.

you can example use row[0].replace(/^[0-9.]/g, ''). replace characters not digits nor decimal points. has no error-checking, think enough in personal spreadsheet.

so i've got simple form in canvas / iframe facebook app, , i'm trying pass along values post. reading on s.o. , fb's latest docs, understand it, data send via post form can accessed on receiving end $_request object. i read on thread on s.o. in order post forms work need pass along input named "signed_request" value current signed_request (i have signed request working ok otherwise...all login , authentication stuff working fine). isnt mentioned anywhere in official fb docs. so problem comes in $_request object signed request, , bunch of other session stuff. form inputs found. the way can read them set method of form "request" isn't real form method. takes of inputs , sends them args in url. horrible. here's sample page canvas app form i'm using try debug (leaving out authentication stuff): <form enctype="application/x-www-form-urlencoded" method="post" target="_top" id="my_form" action=...
