Great, glad my solution worked. Please mark this as the solution and give Kudos if you feel this was helpful.
If the value of any multiple of 5 element is unwanted (i.e. 0.000) you will have to perform a check on the value as well. Of course if the value is not exactly zero you will need to consider a range to check for. There is an function "In Range and Coerce" that will allow you to set upper and lower limits, and outputs a boolean if teh input value is within the specified range limits. This may be helpful.
