I have two simple classes shown below for several userform textbox and spin button controls. Userform_Initiliaze event basically adds any such controls to relevant collections to manipulate later using events. What I want to achieve is to pass text from textbox class (clsTextBox) to spin button class (clsSpinBtn) to increase/decrease the numeric value of the textbox input but I always get "Runtime Error 91: Object Variable or With Block variable not set" whenever I try to spin up or down.
CheckTextBoxValue() is just a function to control and convert any string input into a numeric (double) value.

Any help is highly appreacited!!!
