Well I got it to run by reclassifying both of the two layers into long form. so i have the new transmissivity layer. my next step is to run Darcy's flow. I found a way to side step the problem. but I may have a new problem. Darcys flow needs 4 raster layers, all of which have to be the same cell size and alignment, that is fine, im good there, but they all need to be in float, says the directions. also it says if the residual is too high, my data means nothing and that I should put it through a proper porous medium flow program. I think the effective porosity layer is that layer. I'm going to run this tool once I write down what I've done, if it does not run, I will try your advice on how to change all 4 of my layers to float numbers.
