Hello

I'm new in Smath

I want to do "if δ>0 then k=a+b else k=c+d"

But impossible to include the equation k:=a+b in the "if statement"

When I type "equal" after "k", the "equal" sign is put on the fist line and answer "k-not defined"

I found an exemple on the forum but I'm not able to reproduce it by myself

My test file is attached

Thank you for your help

you have to type ":" (colon) and not "=" (equal)

Thanks
