Eclipse Giving me the R cannot be resolved to a variable error, have tried every fix

I am getting the typical "R cannot be resolved to a variable error" but I have currently tried what I feel to be almost every "fix" and I still can't get it to work. I think it has to do with the many errors I am getting from the res folder:

res\values\styles.xml:7: error: Error retrieving parent for item: No resource found that matches the given name 'Theme.AppCompat.Light'.

res\values-v11\styles.xml:7: error: Error retrieving parent for item: No resource found that matches the given name 'Theme.AppCompat.Light'.

res\values-v14\styles.xml:8: error: Error retrieving parent for item: No resource found that matches the given name 'Theme.AppCompat.Light.DarkActionBar'.

and the many other similar errors that are to do with the xml files in the appcombat_v7 folder.

I have tried cleaning the project, building the project, I have updated my android sdk tools and ADT for eclipse to the newest version, I am using android 4.4 for the target of the project.

any help would be nice
