Problems With UPDATE And DELETE

I have two buttons on my page, one which will update content the other which will delete content from my slq database.

I get this error "CS1501: No overload for method 'updateBlockContent' takes '2' arguments" when I click on my update button.

I get this error "CS1501: No overload for method 'deleteBlockContent' takes '2' arguments" when I click on my delete button.

This is my method for updating - UPDATE [CMS] SET [BlockName] = @BlockName, [BlockContent] = @BlockContent WHERE (([BlockID] = @Original_BlockID))

This is my C# code behind the update button:protected void btnUpdateBlock_Click(object sender, EventArgs e)

{CMSTableAdapter ta = new CMSTableAdapter();

try

{

ta.updateBlockContent(txtBlockName.Text, txtBlockContent.Text);lblFeedback.Text = "Block Updated.";txtBlockName.Text = txtBlockContent.Text = "";

}

catch (Exception ex) { lblFeedback.Text = ex.ToString(); }

finally

{lblFeedback.Visible = true;

ta.Dispose();

}

}

This is my method for deleting - DELETE FROM [CMS] WHERE (([BlockID] = @Original_BlockID))

This is my C# code behind the delete button:protected void btnDeleteBlock_Click(object sender, EventArgs e)

{CMSTableAdapter ta = new CMSTableAdapter();

try

{

ta.deleteBlockContent(txtBlockName.Text, txtBlockContent.Text);lblFeedback.Text = "Block Deleted.";txtBlockName.Text = txtBlockContent.Text = "";

}

catch (Exception ex) { lblFeedback.Text = ex.ToString(); }

finally

{lblFeedback.Visible = true;

ta.Dispose();

}

}

Can somebody please explain why this is happening and how to remedy this problem.

Thanks,

Chris.
