Couldn't resolve the error in user control

It would be nice if you asked a question here clearly, so it was searchable, instead of asking us to look at a bitmap. There's lots of errors there, I'd go back to the client and tell them their code is broken. However, the one you've highlighted, says that you declared a variable twice. All those errors mean what they say, but often one simple error causes a cascading error list as it stops a file from compiling. Look through for that simple error, it's probably at the top or bottom of the list.
