Textfield Validation greyed out

[tschondou]

Hello! I am editing a PDF form for the first time. I am trying to create a text field that only allows numbers. Unfortunately, the corresponding option is grayed out. What am I doing wrong?

What format does you use?

Be sure that you have Number chosen on the Format tab.

If this is the case, maybe show us the format tab settings you are using.  Maybe something needs to be adjusted.  With mine set as shown above, I can access the range options.

My best,

Dave
