Hi Team,

I am binding an expression to multistate Indicator component in 7.9 version and It is not working but same expression is working in 7.3 version.  
I am unable to figure out what’s wrong here.  
Can anyone please help me with this?

Thanks.

ResultNumber=27  
RLSL=10  
RUSL=0

7.3 application returns 1 value and 7.9 version returns 2 value.

Expected value is 1

below is my expression-

if({Root Container.Container 4.Range}=1 && {Root Container.Container 4.Actual.text}!=’’,  
if({Root Container.Container 4.Actual.ResultNumber}!=-999,  
if({Root Container.Container 4.Actual.ResultNumber}\>  
{Root Container.Container 4.RUSL}  
||{Root Container.Container 4.Actual.ResultNumber}\<  
{Root Container.Container 4.RLSL},  
2,1),  
if({Root Container.Container 4.Actual.ResultPass}\>  
{Root Container.Container 4.RUSL}||  
{Root Container.Container 4.Actual.ResultPass}\<  
{Root Container.Container 4.RUSL},2,1)),0)

1. format your scripts when you post using the `</>` button.
2. how is anyone supposed to debug this rats nest of an expression?

I would break this up into smaller expressions, then use a parent expression that uses the smaller child expressions to make it easier to read and debug.

For starters, the inner `if` should probably be (using short names)

```auto
if(ResultPass != RUSL ,1,2)

```

Full simplified version

```auto
if(Range = 1 && len(Actual.text), if(ResultNumber != -999, if(ResultNumber > RUSL || ResultNumber < RLSL,2,1), if(ResultPass != RUSL ,1,2)),0)

```

With value replacements

```auto
if(Range = 1 && len(Actual.text), if(27 != -999, if(27 > 0 || 27 < 10,2,1), if(ResultPass != 0 ,1,2)),0)

```

This logic returns 2 based on your numbers
