Constraining user inputs in matlab

Ephemeral

Anybody know how to constrain user inputs in matlab...

I have 4 probabilities A B C D

Id like the user to enter 3 values within the GUI (partially complete)

A B C

D is always set to <=1

------------------------------------------------

I have a loop like this that uses these values

if Probability <=A
do A stuff
if Probability <=B
do B stuff
if Probability <=C
do C stuff
if Probability <=1
do D stuff

-------------------------------------------------

Scenario 1

The user could enter for instance A as 0.6

This would leave 0.4 to be divided between B and C

Perhaps the user then enters 0.2 (but they cant enter more than 0.4 -- must be constrained)

Then maybe the user enters 0.1

This would mean

if Probability <=0.6
do A stuff
if Probability <=0.8
do B stuff
if Probability <=0.9
do C stuff
if Probability <=1
do D stuff

-------------------------------------------------

So basically within the GUI the user must not be allowed to run with an out of range value... in that case

A could not be more than 1

And having choosen to go with 0.6 as A the user then must define B as less or equal to 0.4

Maybe the only way is to send out an error message and ask the user to re-enter?

I cannot get the box to check the validity of the value itself?

Ok ive sorted this now Cool

All within one menu loop without updating the global variables
