Moving Avg in One Study Not Displaying

Hello,
Im trying to do a tidy little MA script with the 10 21 23e 50 65e all in one study. However, on recent IPOs there isnt enough data for most of these and if the average() returns nothing, it removes my plots of the averages that do return data. Ive tried all kinds of if statements but they seem to execute both sides of the statement and it then invalidates the plots again. Sorry if this has been asked before, but I tried to search and may have not used the right filter words.

Example of script:
Code:
#Establish the 10sma and query whether it is a daily or weekly chart
plot short_SMA10;
def SMA10;
if barNumber() > 10 {
    if GetAggregationPeriod() > AggregationPeriod.DAY {
        SMA10 = Average(price, 2);
    } else {
        SMA10 = Average(price, 10);
    }
    short_SMA10 = if show_sma10 then SMA10 else double.nan;
} else {
    SMA10 = double.nan;
    short_SMA10 = double.nan;
}   
short_SMA10.SetDefaultColor(Color.GREEN);

#Establish the 21sma and query whether it is a daily or weekly chart
def sma21 = average(price,21);
def blah = double.nan;
def graphme;

    if barNumber() < 21 {
       graphme = blah;
    } else {
      graphme = sma21 ;

    }

plot short_SMA21 = graphme;
short_SMA21.SetDefaultColor(Color.CYAN);

@dmw4k4 The crux of the issue is you can't have a tidy little all-in-one study if all of the data isn't available yet... Without a lot of lines of code, your easiest solution is to load multiple MA Studies and let the ones that don't have enough data just sit dormant until they get enough data to display... Sometimes simpler is better... The only reason to combine all of the MA's would be if you are going to take actions based on all of the data which, again, isn't always available... So it becomes a circular problem, kinda like the tail chasing the dog instead of the dog chasing the tail... However, even if the MA's don't display you could still have a dashboard that displays even if not enough dat is available... You could have Green, Red, and Gray (or another color) to indicate not enough data...

Ah okay. I was hoping I just missed a clever trick. Bit frustrating that it just doesn't plot the data that's present but thinkscript has been hard to wrangle for some things for me. Appreciate the response and I'll prob go with data bars for quick viewing. Thanks and have a nice night
