Hi,
First, my apologies for the newbie question š
Iāve been searching for a long time but couldnāt find the answer (might have missed something).
Is it possible, in a module field, to include a simple script as such:
{{ var foo=replace(ābarā;āaā;āeeā);
foo; }}
Thanks š

Sure use the `replace()` [function found in the string section](https://www.make.com/en/help/functions/string-functions#replace--text--search-string--replacement-string-) of the purple header box. It even supports regular expressions if you want a more complex substitution.

Hi Alex,
Thanks for your answer.
Sorry if my question wasnāt clear. In my example, the replace function is indeed used, but itās the use of variables that doesnāt seem to work.
Can I define a variable in a block code just for local use?
And similar question, is there a was to create a simple custom function in addition to the standard one, without having to access external services as described in other questions? (like google apps code, aws, etc.)
Thanks

You can use the set variable or set multiple variables module. Thereās no native way to create code blocks in the system. Some are working on [third party solutions](https://www.make.com/en/integrations/custom-js) but I tend to shy away from those until Make creates a standard way.

And again the answer is no unless you consider a scenario called by a webhook to be a custom function. Make is a no code tool and even though there are logical and functional constructs thereās no concept of a definable function like there is in other programming languages. Maybe one day.

Many hanks for your answers. Thatās what I feared ā¹
Thatās sad, because it could be so much easier to call a function or put a little peace of code in module fields instead of building a factory to do all that.
Is there visibility somewhere on a kind of roadmap/whatās in the plans/if something will be done or not?

Indeed. How I miss that one? @Darin_Patterson is the product lead and he definitely has a pulse on whatās coming to make. And that itās marked as planned is a good sign.
