Sleepy,
I do like your first solution. It works fine now, thanks to your patient instruction. Now if you wouldn't mind going a little deeper with me, I have two new questions.
First, where can I find the phrase "%Calculate%RAND(1,3)%" in the manual? It's that syntax that I would like to have more facility with. I suspect it applies to other functions as well, hence my interest and curiosity.
Second, I had given my six (there were six of them) timer macros more meaningful names than just 1, 2, 3, 4, 5, 6. But I felt it would be simpler for the purposes of this solution to rename them with just the numbers; I don't know why, except that I thought it would be less cumbersome. Am I right? But I would like at some point to return to their original names to retain their meaningfulness to me. Again, I suspect this will have something to do with variables, with which I have little facility but lots of interest. The fact that variables might come into play is exciting to me, as I know that an actual application of them in my "real world", as opposed to a merely theoretical discussion, will more likely cement the concepts in my brain.
In addition, as I was constructing solution 1 as per your instructions I copied and pasted the steps one by one. And as I was doing so I thought there must be a way to simply "call" a previously written macro rather than copying and pasting it step by step into another larger macro. I know there is a way to do this, and I suspect your second solution (which I confess I have not yet digested) actually does this. It's variables, isn't it? I just know it is. I can hardly wait!
Your patience and understanding is very much appreciated.
And my own understanding, if it had a name (maybe a variable?) would say a big thank you.
