Hi... yes, I did initially take the code on this link https://support.digitaltutors.com/ent...cript-lesson-3 That didn't work. I read the forum, before starting this thread.... the one you sent me, but they weren't experiencing the same problem as me and I could not post a question. I didn't think to copy paste their code until you sent it to me again Eventually this was the one that worked // Checks for our Window and Deletes it if (`window -exists Node_Generator`) { delete -window Node_Generator; } // Window for our Node Generator string $Node_Generator = `window -title "Node Generator" -wh 128 256 Node_Generator`; // Define our Row and Column Layout rowColumnLayout -numberOfColumns 2 - cw 2 50; // Column1: buttons Column2: button descriptions separator; separator; button -label "acrLen Maker" -c "CurveInfo()"; text -label "CurveInfo"; separator; separator; button -label "Mult Div" -c "multDiv()"; text -label "Mult Div Maker"; // shows our window showWindow $Node_Generator
