Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding Troubleshooting Function CharacterUseSkill Parameter Problem

I've been trying to make a custom single player campaign recently, but I've ran into a problem with a function.

The intended effect is to have the player activate the polymorph skill during the dialogue once the tag is set through the use of CharacterUseSkill function.

However, the string parameter for the skill doesn't recognize any string values, possibly due to the underscore, but I can't get around it.

Here's a picture for reference. Upper Half is the script written with error compared to the Lower Half with reference to examples in the main campaign.
