Welcome!

Thanks for your help :) I can now say that this bot does work great with combining items. Strung bows quickly without several pauses in between like most bots do.

Thanks for the response. I did try restarting the OSRS client, and RuneMate a few times, but that did not do the trick. I've tried setting the first item to Yew logs x27, and the final item Yew longbow. I've also tried adding knife to the second item, but neither of them work.

I'm having some issues operating this script. Instead of depositing the longbow(u)'s, it's trying to withdraw an inventory of logs when the inventory is full of longbow(u)s
