Heads Pass The Ocean
Switch The Wave & Circle 1/4

The program can't do this because of how you have global flags checked. From the main menu, under 'Other' then 'Option flags' then 'Call execution' you have the following:

    Try center 4 (not checked)
    Reset actives after each line (checked)

Changing the status of either of these should make the above choreography work. However, for your style of choreography, I suggest that you do not change these flags or else you will find lots of other 'bugs' to report.

The reason that the program couldn't do the call is:

Line 1: Heads Pass The Ocean --- it did this fine.

Line 2: Switch The Wave & Circle 1/4 --- The program does not know how to do Switch The Wave from a 1/4 Tag. If you had 'Try center 4' checked, the program would try 'Center 4 Switch The Wave' & it would be able to do the call. If you had 'Reset actives after each line' not checked, the program would retain the active status of the Heads since they just did the Pass The Ocean, hence it would try to have the Heads do the next call (i.e., Switch The Wave), & again the program would be able to do the call.

The problem of course lies in cases such as 'Trade & Circle 1/4'. Do just the Centers do the Trade then all Circle 1/4, or does everyone do the Trade and all Circle 1/4.

My solution to this problem is:

Heads Pass The Ocean
Centers Switch The Wave & Circle 1/4

Okay, now I will explain why the second case works, namely

Heads Pass The Ocean
   Switch The Wave & Circle 1/4

This works because the program considers an indented line to be a continuation of the previous line. The program concatenates the indented line onto the previous line. Hence the above choreography is equivalent to:

Heads Pass The Ocean & Switch The Wave & Circle 1/4

so the program does a Heads Pass The Ocean (and since they are still active) Heads Switch The Wave and then all (since 'Circle 1/4' is an 8-dancer call) Circle 1/4.
