ERROR -- Subcircuit LM324 used by X_U3B is undefined

[kumar143]

Can somebody help me to remove this bug... from orcad

i am using LM324 operational amplifier and this error pops out saying ERROR -- Subcircuit LM324 used by X_U3B is undefined

if i replace this op amp with other one it works fine..

There is something screwed up with method the LM324 symbol placed in your circuit links (or doesn't link, in your case) to it underlying simulation model.

I am sorry Mike..I did not get what you are saying now..In my case it doesn't link to simulation.When I was run simulation,It shows that your circuit had an errors and simulation is aborted.But I can sort out this one with another family of Op amps.
Thanx a lot for u r help
