Thinkorswim education

I am having difficulty finding concise, well orgainzed training materials for Thinkorswim. I've googled and found nothing that was very satisfying. When the help person at Thinkorswim is asked (several; times) the usual answer is something like "Thinkorswim is to complex and convvluted to enable a comprhensive training manual, so just consider individual traing videos that might be apporpriate". I don't believe that constructing a DYI training syllibus is appropriate to such a critical task. So I am looking for suggestions to accomplish my goals. My interest at present is only in stock trading, using personal criteria formulas for stock selection filtering. I have no problem doing this with the Worden TC2000 ploatform, but Thinkorswim remains a mystery. Thinkorswim for Dummies would be great.

I've found lots of stuff through google just by typing in 'thinkscript'.

In the platform, they have swim lessons which is very easy to access
through the chat.

Go to the help tab and there is an icon "thinkDesktop User Manual" (on the right middle). It is their most recently written manual.,100

Variable declaration

I have defined a variable and TOS won't let me use it.
Here is the snippet
def IMHLAmidprice;
switch (timePerProfile) {
case CHART:
IMHLAmidprice = ProfileMid;
case MINUTE:
IMHLAmidprice = if plotsDomain then pc else Double.NaN;
#Tracks Volumeprofile
case HOUR:
IMHLAmidprice = if plotsDomain then pc else Double.NaN;
#Tracks Volumeprofile
case DAY:
IMHLAmidprice = if plotsDomain then pc else Double.NaN;
#Tracks Volumeprofile
case WEEK:
case MONTH:
case "OPT EXP":
case BAR:

I receive:
Value never assigned to IMHLAmidprice at line number

I have been a programmer for 40 years and cant even fathom what is incorrect here.
I have seen other people use def varname; it works.
Is it the switch statement that cant be used this way? I have seen other scripts do this. that is why I am trying this.

It is pretty simple Backus-Naur format.

Thanks in advance

You could try removing the definition for the variable at the beginning and just have it defined inside the Case. I'm not sure this will help, and it's sloppy code, but I don't suspect your script will ever be big enough to notice any performance issues. I've only just began playing with thinkScript, I've got about 10-15 years of programming behind me, and most was self taught and as a hobby, so it's just a thought. Good luck!
