I was merely passing it as with different var name to distinguish from
different attempts in my html. Taking out the other case, as I have
done, has no effect on the results.
This is what is being passed the html in the paste above:
template 'results.tt' => {
'title' => 'Get Softball Season Stats',
'payload' => %season,
}, {};
And this is the result:
Trying with payload
TylerMontgomery(2022) ------------- TylerMontgomery(2022) :
TylerMontgomery(2022)
Name atbats so bb rbis hits runs TylerMontgomery(2022)
