Symbols in number field

    I have a number field and would like the ability to only accept a period symbol in addition to numbers. How can I go about doing this? I tried just using a text field instead, but users were putting commas and dollar signs in their entries and it messes up my export process.

    Do you have a link to your form online?

    You could use a text field, then perform specific validation to return an error when the user does not enter something correctly (check for numbers and 0 or 1 decimal point) or modify the value they entered to strip out any of the bad input. Here is documentation on the gform_validation_hook:
