Try leaving one of the "value" properties empty or removing the attributes altogether using the symbol editor. Then fill in the missing stuff in the schematic editor instead.
ok, i'll try,
thanks! :)

Hi guys! this is my 1st post here..

Hi Teemuk,
i was web-surfing for finding a LTspice IV model for LM3886, and found your interesting work,
so thank you for sharing :)

i copied your text into LM3886.sub , and LM3886.sub into my C:\Programmi\LTC\LTspiceIV\lib\sub
then i started modifying LT1008.asy (a 7pin OpAmp), obtaining my LM3886.asy, and copied that into C:\Programmi\LTC\LTspiceIV\lib\sym\Opamps
then i wired a simple example, try.LM3886.asc, seems to be correctly working..  8)

i'm so NoooB in using LTspice (every SPICE, saying the truth) and experience a strange behaviour..
look at row 42 of LM3886.asy ("SYMATTR Value2 LM3886")
if i comment this row, i'm able to modify the component parameters, but not to simulate because of the attached error,
if i keep this row uncommented, i can't modify component parameters but i'm able to simulate, no errors happen...

error seem to be related to your model,
but i'm not able to understand the cause of this error,
i'm so rookie with it.. but very curious !  ;)
can you kindly help me understanding where's the problem?

Thank You in advance!
bye,
Marco
