onclick openform macro causes syntax error

[gunitinug]

if i click on the left side of existing record it opens a dialog as expected.
But if I clikck on the left side of record not yet created (eg. 3rd row) I get this error message in the pic.



I think I need to modify the onclick openform macro to handle errors. Preferably it will be simple as silently ignoring the error?

the onclick macro is:

OpenForm
   Form Name floater_test
    View           Form
   Filter Name
   Where Condition =="[groupID]=" &[groupID]
   Data Mode   Edit 
   Window Mode   Dialog

[gunitinug]

FIXED add if clause before opening form

if not isnull([groupID]) then   
   openform ....
