spatial analyst - Raster calculator with EVI in ArcGIS

I'm trying to calculate EVI in Arcmap using raster calculator. I put in this calculation

2.5 * ((Float("Band4") - "Band3")) / (Float("Band4") + 6 * "Band3" - 7.5 *"Band1" + 1))

and the output is syntax error. Do you know what I'm doing wrong?
