How To Select Signals

Hi All I'm making a frequency hopping system 10M - 110-MHZ (Simulink)
I have X Freq.s and i want to choose between them by a sequence of numbers but the main problem is how to make a variable sine wave in Simulink (Discrete) but after some time made a NCO but its max Memory is N = 25 and that limit the Max o/p Freq. and tried the VCO but No luck at this also
So i decided to make the wanted Freq.s and select between them so that i made (N Sine Waves & Variable Selector) and i select the wanted freq. by the IDX (by a constant No.) but as i monitored the o/p's of the Variable Selector all the o/p's have signals not the selected one.
So Please If any one could help me to make this system (How to choose one of many signals but from external Index as MUX but with external Selection)?
Thanks In Advance I.G

Use "Multiport Switch" block from the "Signal Routing" library.
