First, I want to Thanks for all the replies.
I figured out the the problem: my coworker tired to introduce another method ( use the back inlets / back detector), but I didn't know that.
Details: I input a valid value (one appropriate flow rate from 0 to 100 ml.min, not the temp setpoints) for the back Det/back inlets, then I could go to further step by click the "apply" or "OK". Luckly I could change to the front inlet from the back inlet.
All the problem fixed.
Thanks for all the gc experts.
I learned a lot from this BBS.

Yes, you are right.
My coworker did change the inlets. that is the problem.
thanks
best
PS: All the replies help me a lot. If could not figure out the problem, the lab should need to pay up to 3000$ for each Agilent engineer's on-site performance maintenance.
thanks a again.
