I've created a web tab that directs to the Drawloop DocGen Run Page with the following URL:

/apex/loop__masslooplus?&reportObject=Dog__c&contactfield=Contact&ddpIds=a18Z00000020zliIAA&deploy=a16Z0000001s5VwIAI&reportForlderId=00l1L000002BIDmQAO&reportId=00OZ0000000tDCCMA2

the org is configured to run Mass via report and I have access to all the folders and reports.  The issue I'm having is that the Run button at the bottom of the Drawloop DocGen Run Page is not highlighted and I'm not able to run the job.
