am i doing this right?

i am trying to count the no of time a value appears in a column for a given event ID. i have written the following code:

private

void TotalChanged()
{
///<summary>
///this procedure calculates the total amount of times the event has been
///modified altogether. the number is read only and written to a text box.
///</summary>int evID = Convert.ToInt32(Request["EID"]);
myda =new SqlDataAdapter("SELECT COUNT (TotalChanged) FROM EventDateChange WHERE EventID = '" + evID + "'", mycn);
myda.Fill(ds3, "ChangedEvent");
foreach (DataRow drin ds3.Tables[0].Rows)
{
int evTotal = (int)dr["TotalChanged"];
Txt_Changes.Text = evTotal.ToString();
}
}

i know the queries ok, as i tested it in SQl Query analyser, but how do i write that value to the textbox called text-changes? everytime i run it i get the errorColumn 'TotalChanged' does not belong to table ChangedEvent.??

Anyone any ideas?? Thanks in advance!

TrySELECT COUNT (TotalChanged)AS TotalChanged FROM EventDateChange WHERE EventID = '" + evID + "'",

This is because when you use COUNT(), there is no column name. After you add AS TotalChanged, you assign the column name to the count.

|||Doh!! Thanks! Works perfectly
