[pmwiki-users] wikiform problem in 2.1.18

[Bellave Jayaram]

I am trying to use the wikiform recipe in pmwiki 2.1.18 using the Templates option but when I put (:wikiform:), all I am seeing is the Submit button. I do have the MarkupExtensions recipe which the wikiform requires. 
 
Has anyone else seen this problem in 2.1.18?
 
Could someone suggest what I need to do to fix my problem?
 
Thanks,
Jayaram
