Hello i need some help
I would like to know how an error appears in a text box when I want to register a number that already exists in the column.
Please, is urgent
I'm not sure I understand - you have a table with multiple rows and you want to make sure the value of a particular column is unique? To do so, you would need to loop through all of the rows in each table and for each one, do another loop looking to see if the value already exists in a row that isn't the current row. I can provide more details if I have identified the scenario correctly.
I am not sure i understand your question fully. If you may elaborate more that would be great. However, simplest way is to use the "for each row" under conditions to look through each line and within the loop use the advanced condition and put if the control in the add/edit state is not empty. And the action show a message, in the message you can choose the nature of the message which should be an error type. Important thing after also is put an action to stop rule execution. If there is an else to your if statement, i advise creating a rule and calling it using the execute another rule comman within the loop. That should sort you out. If it doesnt feel free to reach out
I need it not to save the number if it already exists in the column.
I need more information to configure a control rules.
If you give me an example, how i need to do or configured it, is so urgency.
Here are the general steps, hopefully this can get you most of the way there:
