Hi @ROY,

You can use “String.ReplaceMultiple” from Clockwork

Hi Roy,

You can also consider using DesignScript if you don’t want to download a package.

Sure thing 🙂 You might want to replace the while loop with a for loop.

```
str;
search;
replace;
n = List.Count(search);
c = [Imperative]{
	i=0;
	result = str;
	while(i<n){
		result = String.Replace(result,search[i],replace[i]);
		i = i+1;
	}
	return = result;
};
```

What is the error saying ?

Also, for some reason, Dynamo is interpreting **List** as a variable in your graph.

Did you try String.ReplaceMultiple ?  
It works like a charm.

If you replace **List** with **DSCore.List** it should work.

```
str;
search;
replace;
n = DSCore.List.Count(search);
c = [Imperative]{
	i=0;
	result = str;
	while(i<n){
		result = String.Replace(result,search[i],replace[i]);
		i = i+1;
	}
	return = result;
};
```
