Actually the change has to be done on the webpage because the title on the blue bar is part of the webform. You can relay the information to the other programmer to change the title for your report. The other programmer may be using a generic webform for multiple reports so that the tilte is generic. In that case, you may suggest to have a specific webform for your report with your report title.
The other options are for you to create your own webform. If that is an option, that should work for you.
