Populating a DataGrid on a card problem

Hi all, 
This script: 
   set the dgText[false] of grp "dgVariables" of cd "Variables" to empty 

throws this error: 
Script compile error: 
Error description: round: bad parameter 

And this script throws the same error: 
   put false into HasHeaders 
   set the dgText[HasHeaders] of grp "dgVariables" of cd "Variables" to

At first run of the script it throws the error, but subsequent times running
it, it works. :(
What do I have wrong in the script?
