Setting up MM hex bolts with I logic. I have a question

[corey_danielson]

I am trying to follow McMaster Carr for sizes, the MM are fully threaded until about 60 mm long, then they offer fully and partial threaded. I have a parameter called thread, with a pull-down menu with partial and full. 

LENGTH parameter is length of bolt.

THREADLENGTH parameter is for the thread length 

I want user to be able to select partial or full, but only when length selected in form is larger than is set in the rules

If LENGTH <= 60 Then
THREADLENGTH = LENGTH
Else If LENGTH >= 60 Then
MessageBox.Show("SELECT FULL OR PARTIAL THREADS", "Thread Choice")
THREAD = InputBox("FULL")
	THREADLENGTH = LENGTH
Else If InputBox("PARTIAL")
	THREADLENGTH = 18
End If
