sorry if stupid question, im new , trying hand. code stuck....after point, program ends, no matter whether 1 or 2 selected. know simple im missing....any input appreciated. have copy , pasted section in think problem lies below.

in while loop

while (iscorrect = false){

you using assignment operator, =, it's false.

you want comparison operator == compare if values same.

while (iscorrect == false){

since it's boolean, may want use iscorrect itself:

while (!iscorrect)
