ah! fantastic! right. thanks very much paul for this. I had tried it in
Quotes, but, the tricky part for this obvious still newby in this, was, it
gave me another error when I did this, but I hadn't really twigged in my
head that, ... well that it was a different error, so needed a different
solution! like a left-off right parenthisies, was discovered, that had
caused my code, when that period had been enclosed in quotes, to say
something like "unexpected word let," or something crazy like that. so I
stupidly took it back out of quotes again.


Anywayz, your great and timely input yesterday arvo set me back on the right
track again with debugging and looking for that other error mor properly,
and I've got it working now by end of yesterday evening as desired!
so thanks so much for that man! my total scripting helper once again!
I did have a queery about whether in an if statement, this thing actually
really extracts/chops off, the number of characters mentioned in the
parameter of StringLeft, as it appears to me, at least in the context of an
if statement, that it doesn't, whereas I thought it said in it's description
that it did!
but, suffice it to say that it seems to just examine it rather than lopping
the character off, when the parameter is 1, so there was no need to add the
decimal place bak in, when it did find one as first char on left, as I'd
initially thought I'd have to.

Thanks again.
