Question about Dialogic and text_input

Godot Version

Question

Hi! I am trying to have the player insert a number in the text_input in dialogic so that the player can receive the loan. But it dos not seem to work well. The sommaprestito variable is not recognized as a number, and I get the error E 0:00:12:0901 subsystem_expression.gd:36 @ execute_string(): Invalid named index ‘sommaprestito’ for base type Object
<C++ Error> Condition “p_show_error” is true. Returning: Variant()
<C++ Source> core/math/expression.cpp:1507 @ execute()
subsystem_expression.gd:36 @ execute_string()
subsystem_expression.gd:44 @ execute_condition()
event_condition.gd:27 @ _execute()

What am I seeing in this picture?

it should be about using this plugin:

K… I think I can maybe understand.

You should use the is_valid_float before trying to turn the input into a float?

I have tried this, but it gives me as error E 0:00:14:0316 subsystem_expression.gd:36 @ execute_string(): Invalid named index ‘sommaprestito’ for base type Object
<C++ Error> Condition “p_show_error” is true. Returning: Variant()
<C++ Source> core/math/expression.cpp:1507 @ execute()
subsystem_expression.gd:36 @ execute_string()
subsystem_expression.gd:44 @ execute_condition()
event_condition.gd:27 @ _execute()
I fear is_valid_float is not recognized by Dialogic


In fact it does not seem to recognize it
