Hi,

I am trying to make parameter path in Flex Repeater dynamic but not getting required results,  
e.g.  
`result_val = self.parent.parent.parent.parent.getChild("MainContents_FlexContainer").getChild("CoordinateContainer_Chem_Results").getChild("FlexRepeater").props.instances[i].sample_1`

for above mentioned path I want to convert sample\_1 dynamic as sample\_str(j)  
`sample = "sample_"+str(j+1)`

When I convert whole path to string its giving me parse error for string to number.  
As its unable to read the value from defined path.

Is there any way we can get thode value by putting dynamic parameter in path.

Thanks in advance.

replace:

```auto
...props.instances[i].sample_1

```

with:

```auto
...props.instances[i]["sample_"+str(j+1)]

```

But you probably first want to fetch all instances and then loop over it.

```auto
allInstances = self.parent.parent.parent.parent.getChild("MainContents_FlexContainer").getChild("CoordinateContainer_Chem_Results").getChild("FlexRepeater").props.instances
samples=[]
for i, instance in enumerate(allInstances):
  samples.append(instance["sample_"+str(i+1)])

```

Thank you for your response.  
If we convert it to string, it does not read values assigned to respective path. It gives error as **can not coerce String to Integer**

Still trying to figure out how to resolve this issue.
