Launch URL using textbox value

Tried to pull value from Part Maintenance , Part textbox but couldn’t seem to. So I bound a hidden textbox to the table and am able to get the value I need. But when I run the button code below it errors out. Thanks in advance!

private void btnUpdateRevHst_Click(object sender, System.EventArgs args) {
	// ** Place Event Handling Code Here **
	
	 String s = txtURH.text;  // replacement string s = txtURH.Text;
			
 	Process.Start("IExplore.exe","http://XXXXXXXXX.net/is/UpdateRevisionHistory.asp?Part_Nbr=" + s);
}

Error: CS1061 - line 91 (1220) - ‘Ice.Lib.Framework.EpiTextBox’ does not contain a definition for ‘text’ and no extension method ‘text’ accepting a first argument of type ‘Ice.Lib.Framework.EpiTextBox’ could be found (are you missing a using directive or an assembly reference?)

Post update! Something wrong with the String assignment… I copied the same line from a web site and just changed the string name and textbox name and now it works… Thanks for the help!

C# is case sensitive, so use txtURH.Text;

After staring at the two I finally got it….

Thanks
