How do I maintain proceeding zeros in a text field value?

I just noticed a bug that I need to fix. I have an ID text control that checks to see if you entered a 7 digit number. It works only if your 7 digit value does not start with a zero. For example 0000001 would be a number I would want to enter but that field validation sees only the 1. Is there a way to alter this code so it sees the starting zero and count from there?

If(
 Value(Self.Text) < 1000000 || Value(Self.Text) > 9999999,
 Reset(Self);
 Notify("Reference ID Should be 7 digits. Drop any letters.")
)

Hi @futr_vision

Try these formulas,

If(
Len(Self.Text) <> 7 || !IsNumeric(Self.Text),
Reset(Self);
Notify("Reference ID should be 7 digits and contain only numbers.")
)

(Or)

If(
Len(Self.Text) <> 7 || !IsMatch(Self.Text, "^\d{7}$"),
Reset(Self);
Notify("Reference ID should be exactly 7 digits.and contain only numbers..")
)

Thanks!

Hi @futr_vision

The following should work using IsMatch and a regular expression.

If( !IsMatch(Self.Text, "^(?=.{7}$)[0-9]+$"), Reset(Self); Notify("Reference ID should be 7 digits. Drop any letters.") )

This checks to make sure the value is a 7 digit number and is exactly 7 digits.
