interal and period - question Edit Subject

I want to set a variable, 'multiplier' based on the current timeframe view.

This:

multiplier = (interval == 5 and isintraday ?
1
: interval == 15 and isintraday ?
1
: interval == 30 and isintraday ?
1
: interval == 45 and isintraday ?
1
: interval == 60 and isintraday ?
2
: interval == 120 and isintraday ?
2
: interval == 180 and isintraday ?
2
: interval == 240 and isintraday ?
2
: period == "1D" ?
2
: period == "1W" ?
2
: period == "1M" ?
2
: "blah")

... works for everything, except returns "blah" even when I'm viewing a day, week, or month.

What am I doing wrong with the period() function? It seems to not think that the period is "1D" when I'm looking at the 1D chart.

Also, is this the only way I work out what timeframe is currently being viewed? Surely there's an easier way to determine the currency view?

How do I write the code which is:

"If the current view is 1 Day then set a certain variable to x" ?

I can get it to work for everything (see above) except 1D, 1W, and 1M

My question is, is this code correct:

multiplier = (interval == 5 and isintraday ?
1
: interval == 15 and isintraday ?
1
: interval == 30 and isintraday ?
1
: interval == 45 and isintraday ?
1
: interval == 60 and isintraday ?
2
: interval == 120 and isintraday ?
2
: interval == 180 and isintraday ?
2
: interval == 240 and isintraday ?
2
: period == "1D" ?
2
: period == "1W" ?
2
: period == "1M" ?
2
: "blah")
• No, it's not. The problem in type of the last "blah" literal is string. But type of all other possible values is integer. This is not allowed - types of all branches of operator ?: must be the same (or convertible). So replace "blah" with... say 0 and it would be fine. Also, there should be an indent on the all lines except the first.
