Anyhow, .NET is very good at telling you what your error is, you just need to read it right. In your case, there is a syntax error in your update statement that must be addressed. Presuming you are using SQL server, the best thing to do is to copy the SQL command into the appropriate SQL server tool (management studio or Query Analyizer depending on version) and check the syntax. IT should help you pin things down.
