In case the quick button for Forms on the toolbar doesn't allow you to place the selected form on web-page even if you have the web page unlocked, please do the following:
Add an advanced object to your document instead:
- Click the Insert and Modify tab.
- In the Insert section, click the Object button to open the menu and select Object.
- In the Insert Object dialog box, click a tab to display an object group.
- Click Forms to insert complete forms or individual fields and modules.
- Select the item and make modifications as needed.
- Click OK.
