"For changing the slider range at runtime, use a min and max range of 0..1, and multiply var with the desired maximum value."
So, does this mean:
Code:
itm_qnt_ent_from = itm_qnt_ent_from * item_quant_entFrom;
// with item_quant_entFrom being the
// desired max value, and itm_qnt_ent_from
// being the helper variable.
...
hslider(450, 514, 150, "horizontalSlider.pcx", 0, 1, itm_qnt_ent_from);
