Moving Average relationship scan

[JE $$]

I know this is probably fairly simple but I cant figure it out.
Im trying to create a scan to identify when a fast MA is at least a certain percent below a slow MA

For example:
5SMA(daily) is 10% below 10SMA(daily)

There is a MovingAverageScan in ToS where you can compare the price to a MA, but Im trying to compare a MA to an MA.
I tried messing around with the first line below in the code for Moving Avg scan but I cant get it to work.

So, can anyone help?
Basically just want to scan for stocks whose 5SMA is 10% below the 10SMA as above on daily agg.

Would be used as a mean reversion type strategy

thanks in advanced for any help!

input price = close;
input length = 20;
input AverageType = averageType.SIMPLE;
input percentdiff = 10.0;
input choice = {default "Above","Below"};
def avg = movingAverage(averageType,price,length);

plot scan;
switch (Choice){
case "Above":
scan = price >= avg * (1 + percentdiff / 100 );
case "Below":
scan = price <= avg * (1 - percentdiff / 100 );
}

@JE $$ Save as study and scan

input price = close;
input length1 = 5;
input length2 = 10;
input AverageType = averageType.SIMPLE;
input percentdiff = 10.0;

def avg1 = movingAverage(averageType,price,length1);
def avg2 = movingAverage(averageType,price,length2);

plot scan_up = avg1 >= avg2 * (1 + percentdiff / 100 );
plot scan_dn = avg1 <= avg2 * (1 -  percentdiff / 100 );
