Hi

I tried to use the run script expression in a SQL tag but it does not seem to work and this error “NameError: name ‘app’ is not defined” appears in console. I used the example from the manual on getting the temperature from Yahoo. I am able to get it to work with a label on a window. I am wondering is it possible to use the run script function in SQL tags ?

It is not possible. SQLTags are gateway scoped, so they can’t “see” script module functions within projects.
