Remove single quotes wrapping the variable ConsZeroProj . Use the following code.

ClientScript.RegisterStartupScript(typeof(Page), "ScriptDescription", "<script type=\"text/javascript\"> alert('Error: Consultant " + ConsZeroProj + " projects do not exsist. Please select consultant having projects.');</script>");

It is working, tested at my end.
