Doubleclick campaign manager displaying code

Code preview before the insertion:

<ins class='dcmads' style='display:inline-block;width:300px;height:300px'

    data-dcm-placement='N195601.1098585ULOZTO.CZ/B9417970.141598336'

    data-dcm-rendering-mode='script'

    data-dcm-https-only

    data-dcm-resettable-device-id=''

    data-dcm-app-id=''>

  <script src='https://www.googletagservices.com/dcm/dcmads.js'></script>

</ins>

The procedure of implementation:

1. Copy following part from original Doubleclick code: whole javascript tag:
   
   <ins class='dcmads' style='display:inline-block;width:300px;height:300px'
    data-dcm-placement='N195601.1098585ULOZTO.CZ/B9417970.141598336'
    data-dcm-rendering-mode='script'
    data-dcm-https-only
    data-dcm-resettable-device-id=''
    data-dcm-app-id=''>
   <script src='https://www.googletagservices.com/dcm/dcmads.js'></script>
   </ins>
   
   For proper measurement of clicks in iBB Ad Server, insert following string into code:
   
   data-dcm-click-tracker='%%__REDIRECT%%'
   
   So, code before insertion to Ad Server should look like this:
   
   <ins class='dcmads' style='display:inline-block;width:300px;height:300px'
    data-dcm-placement='N195601.1098585ULOZTO.CZ/B9417970.141598336'
    data-dcm-rendering-mode='script'
    data-dcm-https-only
    data-dcm-resettable-device-id=''
   data-dcm-click-tracker='%%__REDIRECT%%'
    data-dcm-app-id=''>
   <script src='https://www.googletagservices.com/dcm/dcmads.js'></script>
   </ins>
   
   
2. Insert this part as html version of banner into iBB Ad Server:
   
   
3. Rewrite the html version of banner into javascript version by clicking on button "Insert"(document.write form)
   
   
4. Check if the code is displaying (returning) banner in real preview.
