Using Paradox 11 I am running a query to find the difference between two time fields. I have set two example elements using the f5 key labeling them Tp1 and Tp2. Then in another field putting "CALC Tp2 - Tp1". A key field is checked as well. Running the query produces a result with an extra field that contains the text Tp2 - Tp1 in every record for a unique value in the key field , but not the result of the time values that I was looking for. What am I doing wrong?
