Routines ignore Decimals

[cindro]

So I have a field in my table called Amount decimal(12,2)

When creating a Store Procedure/Routine and I try to add a decimal parameter, the length only allows 12 and blocks me from adding comma 2.

When I CALL this Routine, it cannot capture the decimals in the amount submitted.

So, I am forced to use another DB management app to change the Parameter of the Routine to Decimal(12,2).
