Hi,
You can try specifying your own pattern. Select your text box, under properties, you should be able to select a Pattern. Click on it, then create your own validation pattern.
For example, if you want your textbox to only contain a number between 2200 and 2600 (inclusive), you can use the following pattern:
^[2][2-6][0-9][0-9]$
The pattern used here is regular expression, so you can just play with it to get the validation pattern you want. So the pattern above will only match if the first digit is 2, the second digit is between 2 to 6, the third and fourth digit is between 0 to 9.
To trigger that validation, you will still need to insert a condition rule to check if the view or form passes the validation. This method remove the need to use the advanced condition rule.
