FLC TUNED WRONG NAVAID AND FAILED TO MEET XING RESTR CLRNC. CTLR INTERVENED.

Narrative

FLYING FROM MSP TO ORD WE HAD OUR ORIGINAL CLRNC CHANGED A COUPLE OF TIMES. SUBSEQUENTLY; WE WERE CLRED DIRECT MSN; DIRECT JVL; JVL 4 ARR ORD. AT FL240 AND APCHING MSN VOR; I WAS LOOKING AT THE STAR AND ARPT DIAGRAM FOR ORD. I PASSED OVER MSN VOR AND THE FO REMINDED ME TO TURN DIRECT JVL. HE SAID HE HAD THE JVL FREQ ON HIS RADIO SO I DIALED THAT SAME FREQ IN MINE. WE HAD PREVIOUSLY BEEN ISSUED A XING RESTR OF 15 MI FROM JVL AT 10000 FT. THE FREQ THE FO GAVE ME WAS WRONG. ZAU ASKED US IF WE WERE GOING TO MAKE OUR XING RESTR. THE FO IMMEDIATELY RECOGNIZED THE ERROR; SWITCHED BOTH RADIOS TO THE PROPER FREQ; THE DME SHOWING US APPROX 7-8 MI FROM JVL AT FL240. HE REPLIED WE WOULD NOT MAKE OUR XING RESTR WHILE I STARTED THE DSCNT. ZAU RECLRED US TO MAINTAIN 10000 FT AND ASKED FOR A GOOD RATE OF DSCNT. I DSNDED TO 10000 FT AS QUICKLY AS POSSIBLE. ZAU THANKED US FOR THE GOOD JOB GETTING DOWN TO 10000 FT AND WE CONTINUED ON THE STAR VECTORS TO ORD. I ALMOST NEVER ACCEPT A FREQ; RADIAL; ETC; FROM MY FO WITHOUT DOUBLECHKING MYSELF. THIS IS A PRIME EXAMPLE OF THE CONSEQUENCES. THE AIR TFC CTLR DID A GREAT JOB CATCHING THE ERROR AND RECLRING US TO AVOID A POSSIBLE VIOLATION. NO MATTER HOW EXPERIENCED THE PLT YOU ARE FLYING WITH IS; WE CAN ALL MAKE MISTAKES. ALWAYS XCHK YOURSELF. THANKS TO THE CTLR; THE SYS WORKED.
