Print When Expression DOSN'T WO

[faithfultoksa]

Hi 

I applied precisely what explained in in this web page :

 

Using parameters to filter records during report processing

But can't preview the result!!

notice that :

I checked data type in database table and report textfield .. matched OK 

the expression as in previous link like this:              $F{InvoiceValue}.intValue() >= $P{MinInvoiceValue}

[hozawa]

So what's the error message or are you just getting blank page? The formula looks OK to me.

Should be contacting the author of the book if the sample contained in the book does not work.

and show me this error message :

From the error message, it seems like you've defined $F{InvoiceValue} as String instead of as a float.

In screenshot of step 7, $F{InvoiceValue} is shown to be a "Float".

Check that the class type of $F{InvoiceValue} is "java.lang.Float".

i set it as float .. same error message .. 

i correct it many times and same error message
