@Alex It seems to be like a format exception at the line int a = int.Parse((SoccerTable.FooterRow.FindControl("txtAchNumsFooter") as TextBox).Text.Trim());.

In your case, the possibility is that the value return by the textbox is not a valid integer value. Thats why you are getting this error.

Can you try debugging your code and do quickwatch on this statement 'SoccerTable.FooterRow.FindControl("txtAchNumsFooter") as TextBox).Text.Trim()'. Check what you get.
