Mathcad15 - If statement false - > previously defined variable deleted or overwritten with 0 1

variables inside a program are not the same as variables outside a program, You need to define t inside the program

Hi @IRstuff, thanks for the answer.
It is, although, interesting that if you just call the considered "outer variable" in the program (for whatever reason) before the If statement, the considered variable is not erased or overwritten with zero when the If statement is false:

Why would it be? You've written an IF statement that has no ELSE, so nothing happens to t if the IF statement is false. This is one reason programmers avoid naming variables with the same name across function boundaries; it's bound to to confuse the reader and likely to cause mistakes.

The most natural approach IMHO is this:

Sorry - the huge pic size is due to making the screenshot from a 4K display on a rather small notebook display with a rather large windows scale set. Other forum software would allow for resizing but I found no way to do that here. Am I missing something?
Would be annoying to have to manipulate the pic, resave it and then upload.
Are there plans to change the forum software to allow for directly copying pics from the clipboard w/o having to save them first? Would be much appreciated.
