Using FIndControl causing error System.NullReferenceException

[EmmaKate]

Hi,

Having a problem with my FindControl. Want to change the Label value from another aspx page. (Using C#).Heres the code

Label HomeLabel = (Label)Page.FindControl("HomeLabel");

HomeLabel.Text = TextBox1.Text;

This is what is causing the error System.NullReferenceException.

Thanks in Advance
Emma
