Loading text to a string

I'm trying to load text from a .txt file to a string, to use in my level blueprint. To test this, when pressing the q key some words from my text file should be printed ot the screen. However, nothing happens.

Any ideas where I'm going wrong? Here's the code:

.CPP

 #include "MuseumProject.h"
 #include "MyBlueprintFunctionLibrary.h"
 
 
 // Load and save text files
 bool UMyBlueprintFunctionLibrary::FileSaveString(FString SaveTextB, FString FileNameB)
 {
     return FFileHelper::SaveStringToFile(SaveTextB, *(FPaths::GameDir() + FileNameB));
 }
 
 bool UMyBlueprintFunctionLibrary::FileLoadString(FString FileNameA, FString& SaveTextA)
 {
     return FFileHelper::LoadFileToString(SaveTextA, *(FPaths::GameDir() + FileNameA));
 }
 
 
 FString UMyBlueprintFunctionLibrary::FileLoadAndReturnString(FString FileNameA)
 {
 
     FString myString;
     bool myBool = true;
 
     myBool = FFileHelper::LoadFileToString(myString, *(FPaths::GameDir() + FileNameA));
     return myString;
 }

.H

 #pragma once
 
 #include "Kismet/BlueprintFunctionLibrary.h"
 #include "MyBlueprintFunctionLibrary.generated.h"
 
 UCLASS()
 class MUSEUMPROJECT_API UMyBlueprintFunctionLibrary : public UBlueprintFunctionLibrary
 {
     GENERATED_BODY()
     public:
 
     
     UFUNCTION(BlueprintCallable, Category = "save")
         static bool FileSaveString(FString SaveTextB, FString FileNameB);
 
     UFUNCTION(BlueprintPure, Category = "save")
         static bool FileLoadString(FString FileNameA, FString& SaveTextA);
     
 
     UFUNCTION(BlueprintCallable, Category = "save")
         static FString FileLoadAndReturnString(FString FileNameA);
     
 };

The Blueprint

Coding is not my strong point so any help is appreciated.

Thank you! - SB7
