Hello:

If you have not yet solved the problem here is a link that show
a simple setup for ANCOVA including an example. To get an idea
of how to set it up just write a worksheet for the example, make
sure you have it working and then modify it to fit your needs.
It should not take long to write the formulas to do such
an analysis.

While ANOVA is part of the Analysis ToolPak ANCOVA is not.
