help with a GUI number guessing game

[evvo69]

hi, i am a complete newbie on software development onlt a couple of weeks, currently working through a manual and one of the chapter challenges is to create a number guess game in a GUI enviroment. been trying to look for tips on the web to no avail. i am getting a type error: unordable types: int < method<> on line 68. if i could get some pointers would be very grateful
thanks in advance ian

Make sure that both "gnum" and "self.rnumber" are explicitly declared as integers. This error occurs when you attempt to do a comparison (==, >, <, <>, etc.) on two variables which are not of the same type.

[TrustyTony]

You are comparing entered value to method self.rnumber, not integer.

Cheers guys i will try again

A number of things wrong here, see the comments in the code:

Thanks guys, have finlly done it, also fixed the number of tries counter to display the correct number.
