Making forms through numbers or mail merge
This is slightly a work around, but you can use the mail merge function in pages. What you have to do is make a numbers worksheet with variables in your header. Make sure the variables are a designated header.
Put your data you'd like to make a form with in it (numbers worksheet).
Then in pages in your inspector window under the link tab (second icon to left), start making merge variables.
You have to click merge under the merge tab.
Click choose, and choose your spreadsheet with your data.
Click where in the document you'd like to have the variables displayed by highlighting it, and then click the "+" button in the merge tab, similar to how you'd make a form.
Click "Add Merge Field"
Change the variable to the variable you designated in numbers in the dropdown menu (the default will probably be the variable in your list
Once you've marked up your entire mail merged "form, " Click "Edit>Mail Merge."
It will ask you the source and whether you'd like to print it or turn it into a new document. For source choose your numbers document.
You can save the document as a template for later use
Hope that helps!
