Sharepoint designer error

Question

Hello guys,
Scenario
I am using data view control drop down to display data in drop down from a column in sql server and then mapping it to sharepoint list column so that when user goes to create new item he gets the drop down in the form which is getting value from the sql server column...
problem
Whenever i click on data fields of drop down to change the data bindings and give the list column as the data field to save value to i get an error :
Sharepoint designer cannot render XSLT in this data view .
Failed setting processor stylesheet :0x80004005: a reference to variable or parameter 'Pos' cannot be resolved.The variable or parameter may not be defined,or it may not be in scope
Does anybody know what problem is it...let me know if i need to give some more details.
Thanks
