Hi, If we want to create a number only text box we can use the expression

/^[0-9]*\$/             //Number only with no limit

Here we can see a '*' almost end of the expression and why I give '*' means it have no limit. That is we can create any length of text that accept number only.[0-9] Means accept all characters between 0-9

/^[0-9]{10}\$/              // It accepts only 10 digits

If you want to add more digits change the value from braces ({}) to other value.

/^[0-9]{10,20}\$/        //Accepts any digits of numbers between 10 - 20 digits
