Unknown parameter "*" error in LTSpice

[ramuna]

Hello,
I tried to replicate this Youtube video on simulating a triac in LTSpice:

I have uploaded my LTSpice schematic file triactest.asc, and have attached it to this post. On running the Simulation, I get the following error:

Error on line 18 : r:u1:1:_r1 u1:1:n02098 u1:1:trg 1.462* 0.342
Unknown parameter "*"

What am I doing wrong please? Thanks in advance.

PS: The STMicro urls for downloading the Spice libraries have changed from the ones given in the Youtube video.

The new URLs are:

Triacs - STMicroelectronics

ST's TRIAC (TRIode for Alternating Current) portfolio includes devices with voltage ratings up to 1200V, high commutation, high temperature, Snubberless and standard TRIACs, and diacs. Triacs are belonging to our STPOWER family.

Diacs - STMicroelectronics

ST’s Diacs are widely used in consumer appliance applications, such as variable speed hand tools and lighting (in particular CFL), electronic lamp ballasts, electronic transformers for halogen lamps and light dimmers. Functioning as a trigger diode with a fixed voltage reference, the Diac can be...

In both cases, click on the Spice models link & download the zipped libraries.

Thanks to the efforts of Andy, over at the LTSpice User Group, I now have the answer to this problem.
The problem was caused by a typo in the STMicro Diac spice model library st_diacs.lib.
Line 79 of this file is:

R_R1 N02098 TRG 1.462*{Tr}

but which instead ought to be:

R_R1 N02098 TRG {1.462*Tr}

I have attached this file, with its typo corrected by Andy, to this post.

I thank you for your interest in this problem.

Thanks to the efforts of Andy, over at the LTSpice Users Group, I now have an answer to this problem.
The problem is due to a typo in the ST Micro Diac Spice library file, st_diacs.lib.

Line 79 of this file reads:

R_R1 N02098 TRG 1.462*{Tr}

when it ought to read:

R_R1 N02098 TRG {1.462*Tr}

This spice library file with the error corrected, is attached to this post.

I thank you for your interest in this problem.
