I have two fields (Value - InLetters)

if the user wrote in the valu field '2' the InLetters field should be two Egyptian pounds if the user wrote '100$' the InLetters will Hundred Egyptian pounds

 the function is working so good on both web & windows but in infopath code behinde I have many syntacs Errors

Here is me code please correct to me

thanks

You need to initialize the strings before referencing them, and you need to assign the return value before exiting the function
