Try this, give your scripts unique keys and let the framework wrap it in script tags for you.

C#

string Result=rptColumnBAL.CheckDuplicateColumnsBAL(calcDetail);
           if (Result == calcDetail.DisplayColumnName)
           {
               Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "alertInvalidColName", "alert('The column name you have chosen is already in use. Please enter a different name');", true);
           }
 
           else if (Result == "")
           {
               Session["CalcFormula"] = calcDetail.calculationFormula;
               Session["DisplayColumnName"] = calcDetail.DisplayColumnName;
               Session["UseDividendIfZero"] = (cbDividend.Checked == true ? true : false);
               Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "CloseWin", "close();", true);
           }
          else
           {
 
               Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "alertInvalidFormula", "alert('The formula you created already exists under the column name: " + Result + "');", true);
           };

Also you had single quotes all over the place so chances are your script was being rendered but just causing errors when it ran.
