ok no problem,,
but i m typing this u can read it later ...........
actually that MR is always greater than 4 (MR>4),,if this condition is false then it show error message ,and obviously when i run program value of MR is always 0,so it shows error ..and then i click on the "ok" button of dialog box then also still that value of MR can be increase by user,until the condition MR>4 is not satisfy.. and also when MR>4 (means 5,6,7...) then it goes in true condition,,and when user decrease the value of MR (means below 4,3,2,1,0) then it again shows error message..
sir this is my main vi of my project in this block diagram of this vi,there are more than 15 -20 sub vis are running and this MR is common for all vi's
i msending you this vi and inside it another sub vi, that shows the 5 position and its reverse sequence that u solved already..
The untitled new.vi is the main vi of my project and input-sequence new.vi is my sub vi so i dont want to use while loop in sub vi,,no need for that ,,and main vi should be run continuosly until we stop it if the error is also occured ..
