TOPIC:

Hello, I have managed to get it to work but I need that when it finds a duplicate value, it just warns but allows to continue with the form. The thing is that this form allows it to be modified from ContentBuilder and due to this code that it gave me when editing the form it gives an error. I have tried to change the code:

echo 'false';
exit;

by:

echo 'false';
continue;

But what happens is that it does not show the duplication notice.
Can you tell me what I'm doing wrong?

o show a warning if a value is repeated, you can use a conditional statement to check if the value already exists in a list or an array.knowledgeforu.info/sehat-card/ Here's an example in Python:

my_list = [1, 2, 3, 4, 2, 5] # example list with a repeated value

if len(my_list) != len(set(my_list)): # check if there are any repeated values
print("Warning: There are repeated values in the list.")
else:
print("There are no repeated values in the list.")

In this example, we use the set() function to remove duplicate values from the list, and then compare the length of the original list with the length of the set. If the lengths are not equal, then there are repeated values in the list, and we show a warning message.

You can modify this example to suit your specific needs, such as checking for repeated values in a database or a file, or displaying the warning message in a different way.

I don't understand this answer nor what does the link that appears mean. @TheMuffinMan can you review my query?
