How to convert String to Integer in iMacros? -

i trying use javascript , imacros together. trying increment loop 4 everytime, that's why using javascript

below javascript code

iimdisplay("start loop..."); j=4; k=2; l=73; m=72; n=1;  (i = 0; < 10; i++) {       iimset("firstone",j);     iimset("secondone",k);     iimset("thirdone",l);     iimset("fourthone",m);     iimset("fiveone",n);     retcode = iimplay("addcommerceattributes");      j = j + 4;     k = k + 1;     l = l + 1;     m = m + 1;     n = n + 1;      if (retcode < 0) {         report += ": "+iimgetlasterror();         alert ( report );     } } iimdisplay("complete"); 

below imacro

version build=7311339 tab t=1 tab closeallothers    url goto=https://example.com/admin/commerce  tag pos=firstone type=td form=name:bmform attr=class:list-field extract=txt tag pos=secondone type=input:radio form=name:bmform attr=value:4 extract=checked tag pos=thirdone type=input:radio form=name:bmform attr=value:0 extract=checked tag pos=fourthone type=input:radio form=name:bmform attr=value:2 extract=checked tag pos=fiveone type=input:radio form=name:bmform attr=value:5 extract=checked  saveas type=extract folder=c:\myfile file=modifyattributes 

i getting error

badparameter: expected pos=<number> or pos=r<number>where <number> non-zero integer parameter 1, line: 18 (error code: -911) 

looks when pass values javascript imacros , converting string. need convert integer? if yes, how that?

thanks in advance !!

you need put variables inside {{....}} imacros knows variable. work:

change:

tag pos=firstone

to:

tag pos={{firstone}}
