this seems like such a novice question I'm embarrassed to post it.
But I've been unable to resolve it or find the answer by searching.
I have a form with number fields and want to specify a minimum value
WITHOUT an upper limit. The validate tab allows me to set a range,
such as 50 - 1000, but I just want it to be over 50.
I've tried placing 50+ or >50 in the "TO" box, but it does not accept this.
I suspect I need a custom validation script but I'm not familiar with doing this.
I'm using acrobat 8. I appreciate any advice, thank you.
I knew it would be so simple that I would feel like a fool.
I had tried this, but leaving the "TO" box blank caused acrobat to insert a 0 which implied to me it would not work, so I never tested it. Following your post, I have now tested it and can confirm it works perfectly.
