Help needed: Scripting error.

[Nonnatee Kanjana]

Hi,

The code seem to be working by itself. However it kinda broken when frappe takes it to render. 

Could someone kindly help me out with the following error. I have spend countless hours trying to debug error.

[Error] TypeError: 'null' is not an object (evaluating 'document.getElementById('barcode_div').innerHTML = DrawHTMLBarcode_Code39(cur_frm.docname, 1, 'yes', 'cm', 0, 10, 0.5, 2.2, 'bottom', 'center', '', 'black', 'white')')
 eval code (undefined, line 4)
 eval
 run_embedded_js (frappe.min.js, line 1668)
 render (frappe.min.js, line 1653)
 build (frappe.min.js, line 1651)
 (anonymous function) (frappe.min.js, line 1532)
 dispatch (jquery.min.js, line 3)
 handle (jquery.min.js, line 3)
 trigger (jquery.min.js, line 3)
 (anonymous function) (jquery.min.js, line 3)

 (anonymous function) (frappe.min.js, line 540)
 dispatch (jquery.min.js, line 3)

the DrawHTMLBarcode_Code39 function

function DrawHTMLBarcode_Code39(data,
        checkDigit, humanReadable,
        units, minBarWidth, width, height, barWidthRatio,
        textLocation, textAlignment, textStyle,
        foreColor, backColor)

and help to correct this issue is much appreciated. I have been banging my head against the wall for several day.

Thank you.
