My bathyub is clogged but someone told me that since I only have 1 screw on my drain linkage (thats mounted to the tub) that that may be my problem.

No! While the linkage may not operate correctly with just one screw it won't clog your drain unless it's stuck in the closed position and won't allow it to drain. Can you work the lever up and down? Let me know, Tom
