Hi, i've had a quick search on here and can;t find a thing about this, and googled it extensively too, my issue is this. I have an input Control for a report that is linked to a parameter of type BigDecimal, the data type is number between -90 and 90 and the initial validation seems to work. ie "Fish" - You must enter a valid floating point number -100 - Number outside of range -10 - Validates fine. etc. Now the issue comes if I enter a valid number within range that has a decimal point in. If I do this the value get's through the first stage of validation but then I get this error: I don't think the BigDecimal here is linked to the parameter data type becasue I tried changing it to a Double and got the same BigDecimal error.
