Hello Carisa,

Define a random variable:
    i = {0:3};

Define the global variables:
    specie = ["Cedar","Douglas Fir-Larch","Spruce-Pine-Fir"];
    unit_weight = [3400,4800,4100];

In the calculations, use:
    unit_weight[i]

In the question text, use:
    {=specie[i]}

Hello John,

In fact, regarding arrays, there is at least one other, arguably more intuitive way to solve your problem. I'll post it a bit later.

... dynamiccourseware.org site is being blocked...

People in IT departments act in a way that seems to us, poor laymen, sometimes surprising. I don't know why they would do that. They may not like the site name or the theme's blue color. Who knows?

Seriously, dynamiccourseware.org ↗ is based in Montreal, Canada. It is hosted at the École de technologie supérieure, the “faculty of engineering” of the “state” university of the province of Quebec. It uses US-based Web-Stat ↗ analytics, which gives me an idea of its usage. Here is how the Web-Stat 'General Data Protection Regulation' (GDPR) settings for dynamiccourseware.org are set:

So dynamiccourseware.org complies to the General Data Protection Regulation:

• All visitor's IP information is anonymized by truncating the last digits of the IP.
• No cookies are written on any visitor's computer.

I have made public the traffic statistics on dynamiccourseware.org. You can find them at https://www.web-stat.com/public_stats/DynamicCourseware.htm ↗. Since April 2022, the site has been visited over 10,000 times by people from over 100 different countries.

dynamiccourseware.org is free and does not depend on any commercial enterprise. No advertising is displayed on the site. No defamatory or inappropriate comments have ever been posted on the site.

Perhaps you could inquire with your IT department. If you get the reason why the site is blocked, I will try to remedy the situation if it is my responsibility.

Hello John,

Here is another method, probably a little more laborious than the previous one but perhaps a little more intuitive.

It is useful to think of data in arrays, for example like this:

For latent heat:

For sensible heat:

Let the random variables i and j define the rows and columns in the table:

i = {0:3};
j = {0:3};

Define global variables as follows:

# Pick the activity and the temperature:
activity = pick(i, ["seated at rest","doing very light work","doing sedantary work"]);
temperature = pick(j, [24, 22, 20]);

# Pick data for the picked temperature:
lat = pick(j, [33, 50, 80], [28, 42, 70], [21, 36, 62] );
sen = pick(j, [67, 70, 80], [72, 78, 90], [79, 84, 98] );

# Pick latent heat and sensible heat for the picked activity:
latent = lat[i];
sensible= sen[i];
