Can text be included in an if statement? For example: If "Thin-walled pipe anchored throughout" then P=1-v. I have various conditions that different formulas would be used depending on the conditions, see below.

I don't understand how to input the data into the statement. If I press the space key, the input ends, and I cannot input anything.

If I press the space key, the input ends, and I cannot input anything. There is no space key to press. Construct the snippet, done.

The cases() function is included into the "custom functions" plugin, so you should also be sure to have it installed.

I had the "custom functions" plugin installed, but the use of it is not in any of the manuals, at least not that I could find. I had no idea I had to type the word "cases" to get to the input.

Jean I use the cases function to type everything in, but when I go back to the first line that says "x if str", as soon as I type "x if str =, as soon as I type the = sign, I get "x not defined". I am trying to understand, but not getting it yet. I had it almost working, but then this glitch appeared.

But it does not really work, because if I say str:="b" and x:=7, the answer is 21.99 instead of 14, but it does allow me to type it. I am confused.

In the second column of cases you have to use boolean equals, not the assignment operator. You can find the boolean operators in one of the palettes on the right of your screen, hovering the mouse hover the symbols you should see the keyboard shortcut. |

I tried backspacing, and it did not work.
