I am creating a XOOPS Form and building a XoopsFormElementTray() where I can add multiple radio buttons and text fields to appear in the one form column.

But I dont know how I can add text to appear directly AFTER a text field.
e.g. Recurs every TEXTFIELD days
(where TEXTFIELD is a XOOPS form text field and "days" appears on the SAME line as the textfield)

I thought I could use something like setDescription() but that doesnt seem to work. I think that function only adds a description underneath a left column form element label.

Is there another function for just adding text to a XOOPS form?

Well I figured out how to do it - all about specifying the delimiter parameter in
XoopsFormElementTray ($caption, $delimeter);

I had the delimeter set to "<br />" - changing the delimeter to be a space allowed me to combine multiple form elements on the same line, using the XoopsFormLabel() function to add text in bettwen elements.
