pop up menu in GUI that connected and read from .mat file

i have 3 pop up menu that related and connected each other, at first i have 1 structure that contain 2 member data (save under the name car.mat).

let say: Car.truck.a=[5,6,3;1,1,1] Car.truck.b=[2,2,2;1.9.7] and Car.jeep.c=[10,20,30;6,6,6] Car.jeep.d=[7,7,7;0,2,4]

the 3 pop up menu are related, for example if i chose popup1 the string is jeep and truck, then after chose 1 ,let say i chose jeep, then the 2nd popup menu (popup2) pop up menu option become c or d, then after i chose d, the pop up menu option become (1,1), (1,2), (1,3),(2,1),(2,2) and (2,3). then after i chose (2,1) the value of text is 0.

how can i built this kind of case?? please be more specific, cause i'm a beginner... :) thank you

set() the pop-ups Enable property to be 'off' to start, except the first one. As each pop-up is used, it should set the next one's Enable to 'on', and set the String property to fieldnames() of the next layer.

What error do you encounter when you attempt to program this yourself?

[Luhur]

i have no idea about the script.

[Walter Roberson]

Start at the beginning: how do you set the Enable property of those items to be 'off' ? And how, in a callback, do you set the Enable property of one of them to be 'on' ?

would you mind just giving me the demo or an example that similar to my application??
