Cannot read property "0" from undefined

[basantsoni]

Hello Friends,

I’m facing error messages when we are reading and printing all array values from for loop.

I have stored true/false fields into array.

Hello there,

try something like

gciscpD['checkboxes[i]']

or gciscdP[newVar], where newVar is taking the checkboxes[i] value into the loop.

for(i in checkboxes){
   newVar = checkboxes[i];
   gciscpD[newVar];
}

Hi Basant,

this happens when you are trying to access something which has not that property

try below and check whether error comes or not

gs.info('Following Array Values : ' + gciscdP[checkboxes[i]]);

Mark Correct if this solves your issue and also mark Helpful if you find my response worthy based on the impact.
Thanks

   Caused by error in script at line 12

      9: 		var nm = gr1.name;
     10: 		var len1=[];
     11: 		len1 = nm.split(' ');
==>  12: 		var cc = len1[0];
     13: 		var cod = new GlideRecord('u_country_code');
     14: 		cod.addQuery('u_code',cc);
