Check if a text field contains any numbers

When using a text field, you can use the following template to check whether the field contains any numbers and display a message of your choice. 

Create a calculation field in the study form using the calculation field example below - remeber to replace 'variable_name' with the variable name for the text field. You can also update the messages shown to display the wording you prefer.

if ((/\d/).test('{variable_name}')) { 
    "The entered value contains numbers."
} else {
    "The entered value does not contain any numbers."
}

Test the calculation in the calculation helper.
