Hi Saba and Jens,
":" are not needed, they are optional, see

http://www.cheetahtemplate.org/docs/users_guide_html/users_guide.html#SECTION000680000000000000000

Maybe it's a problem with the left quotes around Use_Snapshot in the #if line?

Hi Saba,

there is a syntax error in the line of the "#if". Please add ":" at
the end and report whether the error still occurs.

All the best, Jens

BETREFF: [galaxy-dev] Running a different command based on selection
in the tool

Hi all,

I am trying to write a tool that based on user criteria will run a
different script.

In the code below, If I select Use_Snapshot, I see the right interface
but somehow galaxy tries to execute the #else part and look for "m"
input parameter. The example I have seen in documentation is using the
script with same name in both if and else and the number of input
arguments is the same as well. Any suggestions/ideas why always #else
part gets executed although right interface appears based on user
selection.

Thanks,

Saba
