count on crystal report

[sugeng]

Select count(id) from table where company_id='"& textbox.text &"'

How i can formulate it in crystal report?

i've formulate in SQL Expression Field - Selection Formulas - Group Selection but there's an error "a number required here" the cursor sign at {?CompanyID}.

Count ({table.id},{table.company_id} = {?CompanyID} , "")

whats wrong??\

thanks

It seems that you have to declare numeric data type the parameter because the field 'company_id' is numeric
