lblMessage.Text = "Your Record(s) Have been Updated";
command.Connection.Close();
catch
lblMessage.Text = "Your Record was not updated please try again";
Thank you for your help

To expand on Mike's advice.
Change your catch to:
catch(Exception ex)
{ // Break point here
lblMessage.Text = "Your Record was not updated please try again";
Put a break point in where the comment says.
Run it.
Hover over ex or add a quickwatch ( right click it ) and see what the error and inner exception is.
I see several problems though.
You have way too many parameters and Age should be int.
They are objects  - they have a type.
It'll be a string with your code there.
Something more like
command.Parameters.Add("@Age", SqlDbType.Int);
command.Parameters["@Age"].Value = Convert.ToInt32(txtAge.Text);
Although that might not cut and paste, it's air code intended to give you the idea.
Hope that helps.
