How to make sure there's no commas in a text field?

[BowDown]

I want to set up a validation by calculation that will check to see if the user has entered a comma in a text field. I'm having no luck doing this.. can it be done? If so can someone help me out here?

Thanks!

Have a look at the filter function. That may help

You can have an Auto-Enter calculation on the text field. Be sure to uncheck 'Do Not Replace Existing Value for Field...). The calculation would be simple:

Substitute ( thisField ; "," ; "" )

This will simply remove them. Why bother a User with a validation error when FM is bright enough just to zap those commas from the universe?

Hi,

What you want to do if a comma is found will dictate which way is best. However, the patterncount function can be used to count the # of commas, the position function can be used to tell where in the string the comma occurs, the replace function or the substitute function can be used to replace the comma with a space.

If you do not want to allow a comma to be entered then place this calculation in the validate by calculation ....

If not (patterncount(fieldname,","))

Should do the trick.

Hope this helps,

Tim

I concur with Laretta that you should just use a substitute to remove those commas. Once the field becomes comma free then you can use the number formatting option to allow commas for diplay purposes.

Awesome guys. I figured the substitute thing out from a quick search on yahoo. Works great. I swapped the comma for a dash. Figure it would serve the same purpose.
