error when running "grunt" in command window for project - Up and Running with Grunt video tutorial

I've been watching the "Up and Running with Grunt" video and set up my project files as shown in the video. Everything installed correctly and I configured the gruntfile.js with my first task exactly as the video showed, which is to uglify all my .js files. When running grunt in the command window for my project I get this error:

Running "uglify:build" (uglify) task Warning: Cannot read property 'filter' of undefined Use --force to continue. Aborted due to warnings.

Has anyone by chance seen the video, tried the steps and run into the same issue? Any ideas why the error is occurring?

Thanks in advance.

Hi Brad,

I found the problem. classic case of misspelled word: scr should have been src for the source files!
