How to resolve MATLAB 2014a Simulink error "must be monotonically increasing"?

Hi, 

Currently, I am using MATLAB 2014a Simulink version. I want to generate PWM pulses for a switch. I am using repeating sequence generator and sinusoidal signal from sources library. Both are from simulink blocks category only. When I run the program.. following error appears..

"Values of BreakpointsForDimension1 in 'pv1/Repeating Sequence/Look-Up Table1' must be monotonically increasing. The problem occurs at the number 3 breakpoint. Please change the breakpoint data or use the fixedpoint tools such as Auto Scaling or Fixed-Point Advisor to determine a different parameter dialog type'.

same simulink file worked well in MATLAB 2012b version. I tried different suggestions, but did not work. Give me some suggestions regarding this.

Thank you.

Order Values of BreakpointsForDimension1 in 'pv1/Repeating Sequence/Look-Up Table1' such that

value(1)<value(2)<...<value(n)<...

Repeating sequence will generate repeated values at regular intervals of time.. It wont give "value(1)<value(2)<...<value(n)<.". But the block available in simulink... I dont know why matlab placed such block if it wont work.

The independent variable (I guess time) has to be ordered, not the dependent variable.
