I want to pull a value from a field and perform calculations on it but if the field contains any non-numeric characters I want it to do nothing.

You can use a regular expression for this. For example:

var v = this.getField("Text1").valueAsString;
if (/\D/.test(v)) {
    // the field contains non-numeric characters
} else {
    // the field is empty or contains only numeric characters
}
