I made a form in Base that has a subform which requires input of a date field and a number. I defined the fields for the subform table as a [DATE] field and as a [NUMERIC] field. I can add data directly to the table and it is displayed OK in the form but when I try to save a new record in the form I get this error message "java.lang.NumberFormatException" It must have something to do with the numeric fields. It must be simple to fix, but I haven't found a solution yet. Any help appreciated!

There are many ways to generate that error. Your question does not explain what controls are being used on the form to input the data. For example, if the table field is numeric and the form is a TextBox and you enter a date, the error will occur. Likewise, if the table field is numeric and the form is a TextBox and you enter "a1" you will get the same error. You can set a table field as a number, format the column as Date, have it display correctly in a TextBox and when you try to enter a different date for that field on the form it will generate the error.

Without further information on your exact setup, look that your form input fields are in sync with the actual table field definitions.

Hi Ratslinger, thank you for your answer, that gave me a clue where to look and I used it to narrow down the error area and to fix the field definition in the table. I selectively left some field blanks to find out which one caused the error. It was a [NUMERIC] field that was causing the problem. I replaced with a [REAL] number in the table and that did it! Don't know what the difference is between these well enough to tell which one will work or not but replacing the type of number handled.
